Their orbital and rotation period, the elements they are produced up of, the Atmosphere, the distance from the sun, size, and appearance all are distinct from each and every other. Saturn has a gorgeous ring, the earth has a life, the Jupiter has number of moons, some move around the sun clockwise some anticlockwise.

Pluto is the smallest planet, which was discovered within the solar system orbiting the Sun. It truly is even smaller than the moons of other planets. Now it truly is one of the 3 “Dwarf Planets” other two being Ceres and Eris. All it is possible to discover on Pluto is rocks and ice of ethane, methane, carbon dioxide, and nitrogen. Here are some far more facts about Pluto:The Planet is discovered in 1930, which is the smallest and distant.You can’t see it along with your naked eyes, telescope is necessary to the planet. As well as with telescope you may only see the star like object inside the sky. It looks yellowish-brown.The Atmosphere on the Pluto is extremely cold. When Pluto is away from the sun the atmosphere get frozen and when close the temperature gets elevated and frozen methane, Nitrogen, Carbon dioxide melts away.The surface temperature of the planet is really cold in between -235 and -210 degree C.The orbit of the Pluto is really various from any other planet in the solar program. It really is far from the circular of other planets. Sometimes it also gets closer to the sun than the Neptune. This happens soon after every 288 years.Although the orbits of Neptune and Plato cross every other, these two planets can’t collide.The rotational period of Pluto is 6.five days and orbital period extremely eccentric i.e. 90,613 days.The Diameter is 2340 km and the density is less than half of the earth.The distance of planet from the sun is 39.five times the distance of earth to the sun.No spacecraft has been sent as but, “New Horizon” by NASA has been launched to reach in 2015 despite the fact that.Charon, Nix and Hydra are the moons of the planet. Charon is biggest as well as other two small. James W. Christy discovered Charon. Each Caron and Pluto are tidally locked to each other. They’re constantly faced to each other. Ahead of 2006 Pluto was considered as the ninth planet of the solar system but following discovery of comparable objects nearby it really is included in new category “Dwarf Planets”. It has been numbered 134340.

Pluto, the tenth-largest body found to be revolving about the Sun, is the second-largest dwarf planet. Pluto, which was previously a planet, has lately been classified under the members of the Kuiper belt. Pluto is now the largest member of the Kuiper belt region. Let us look at some intriguing details about Pluto.

10 Fascinating Details about PlutoThere is an fascinating story behind the discovery of Pluto. Researchers had been observing a disruption in the orbit of Uranus considering that a long time. They believed it to be brought on by some celestial physique other than Neptune. Percival Lowell and William Pickering began researching the subject. They had managed to acquire two images of Pluto but they had been unaware of their brilliant discovery. The incredible truth is that the name ‘Pluto’ was suggested by an 11-year-old girl of Oxford, England, Venetia Burney.Pluto is composed of rock and ice and has one-fifth the mass of the Earth’s moon. Its eccentric nature takes it from 30 to 49 AU from the Sun, therefore causing it to occasionally come so close to the Sun, that it surpasses Neptune in its proximity to the Sun.The orbit of Pluto is very inclined and strikingly distinct from the orbits of the other planets. For every single three orbits of Neptune about the Sun, Pluto makes two. The two bodies return to their original positions and the cycle of orbiting repeats. Each and every cycle takes 500 years to complete.Pluto is composed of rock and ice. It’s brownish yellow in color. Its atmosphere is inside the type of a thin envelope of nitrogen, methane and carbon monoxide. As Pluto moves farther from the Sun, its atmosphere freezes and as it moves closer, the ice sublimates to form gas.Some studies say that if Pluto had been closer to the Sun, it would have been a comet. Being composed of rock and ice, it wouldn’t have last long in proximity of the Sun.Pluto has 3 natural satellites of its own. Charon was found in 1978 although the other two satellites namely, Nix and Hydra were located in 2005. Pluto’s moons are exceptionally close to it. Scientists say that the Plutonian program composed of Pluto and its satellites is really compact.When one of the natural satellites of Pluto passes in front of the Sun, it blocks light to Pluto. This causes an eclipse-like phenomenon on Pluto. An eclipse can happen when the orbital nodes of 1 of Pluto’s satellites aligns with all the position of the Sun as observed from Pluto.Based on Western astrology, Pluto is the ruling planet of Scorpio. Pluto is regarded as to be spending around 21 years in every zodiac sign. Pluto is believed to represent that portion of an individual, which destroys so that you can renew. Pluto is stated to govern organization, wealth and detective work and is associated with extreme power.Several consider that Charon revolves around Pluto. Nonetheless, in reality, Pluto and Charon together orbit a frequent point in space. The typical point around which Pluto and Charon orbit exists above the surface of Pluto. This phenomenon produced the astronomers believe of classifying Pluto below a binary planet program.Each day on Pluto lasts for 6 days and 9 hours, meaning that it has very much less speed of rotation. No spacecraft has yet landed on Pluto. Even so, in 2016, a spacecraft might land on it. We can hope for 2016 to witness the making of history!

When I was growing up, there had been supposed to be 9 planets inside the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There were also different other celestial bodies including asteroids which formed the asteroid belt that lay in between the planet Mars and Jupiter as well as the various ‘moons’ which had been pulled by the gravitational pull of each planet. And of course the Sun, which ran the entire show, apart from becoming the protagonist of what we call the Solar Method. But lately, there was some kind of convention on our humble planet that felt that Pluto did not quite make the grade as a ‘planet’ and stripped it of its planetary status. Therefore, inside the light of all these events, the frequent individuals around the globe can’t help but wonder, is Pluto a planet?

Is Pluto a Planet or Not?

Before we get down to whether or not Pluto is actually a planet, let us do a bit of background check on Pluto. Pluto or 134340 Pluto as it was formally known, was very first found in 1930. It was immediately accorded the status of a planet, as it seemed like a celestial body which orbited the sun. Later a group of specialists within the field of astronomy began questioning the correctness of labeling Pluto a planet. In the 1970′s, astronomers started locating more celestial bodies beyond Pluto, notably 2060 Chiron (not to be confused with Pluto’s moon Charon), which fueled a debate for the very first time about the inadequacy of Pluto to be known as a planet. The topic went hot and cold for some years till in 2006, a convention of the International Astronomical Union (IAU) decided that there ought to be a formal definition for the word ‘planet’. To be a planet, a celestial physique ought to have the ability to possess specific characteristics. Regrettably for Pluto, it did not get the pass marks in all of the required criteria and therefore was relegated to being a ‘dwarf planet’.

The criteria that the IAU wanted each and every celestial physique to meet had been.The body must have its orbit about the Sun.It really should be spherical by the merit of its own gravitational force. Meaning, its gravity need to have the ability to pull itself into a shape which is spherical.It ought to be the biggest, most gravitationally dominant planet in its own orbit.The IAU ruled that Pluto does not qualify the third criterion and it does not qualify as a planet. So regrettably for Pluto and its founder, Clyde W. Tombaugh, Pluto is not a planet. It’s now officially a ‘dwarf planet’.

Public Reactions

The confusion regarding is Pluto a planet, is further fueled by state governments inside the United States. Illinois and New Mexico in specific appear to be totally fine with denouncing the ruling of a worldwide body of astronomers and wish that Pluto be given back its planet status. They think that there is certainly a sentimental value attached among the individuals who grew up understanding that Pluto is a planet and it really is unduly harsh to strip a planet of its status in such a way. They also claim that not all the members had been present in the meeting which ruled that Pluto is no longer a planet so justice has not been done to the now dwarf planet. Not to mention that they do not want Clyde W. Tombaugh, a resident of both these states, to be identified by posterity as somebody who discovered what’s ‘just’ a dwarf planet. To this day, these two states insist on celebrating March 13, as ‘Pluto Planet Day’.

Read on for a lot more info and fascinating articles on our Solar Method.How A lot of Planets are ThereInteresting Facts About the Solar SystemFacts about Dwarf PlanetsSo I hope which you are now clear about is Pluto a planet? In case you will be nonetheless unsure, I’ll wrap this article by saying: ‘No fellas. Not any more’.

Proper from its discovery in 1930, till 2006, Pluto (formally known as 134340 Pluto) adorned the status of a planet. Pluto was regarded as the ninth planet of the solar system, which was also the smallest as well as the most distant one. Nonetheless, in the course of the 1970s, the discovery of a minor planet 2060 Chiron and also the recognition of the low mass of Pluto, raised doubts concerning the planetary status of this erstwhile ‘planet’. Later, with the onset of the twenty very first century, many more minor planets were discovered and 1 of them (Eris) had been much more massive than Pluto. All these facts led to the formulation of a definition for the term ‘planet’ and Pluto did not fit the parameters of a planet. In short, right after the convention of the International Astronomical Union (IAU) in 2006, Pluto was stripped off its planetary status and demoted to the status of a dwarf planet (having a new number 134340), together with other minor planets, like, the Eris, Ceres, etc. However, the debate relating to the planetary status of Pluto is nonetheless on, as a lot of scientists still think about it a planet. Read on to know more about some fascinating Pluto facts.

Facts About Pluto

Now you’ve got a basic thought about its discovery, history and status. Pluto may be the second-largest known dwarf planet in the solar technique; the tenth- largest body identified to be revolving about the sun in an orbit along with the largest member of the Kuiper belt. The following Pluto details can assist you to refresh your understanding about Pluto.Although the efforts to find out the ninth planet was done by researchers named Lowell and William H. Pickering, it was Clyde Tombaugh, who became successful in discovering Pluto.The name ‘Pluto’ was suggested by a nine-year old school girl known as Venetia Burney, of Oxford in England. The naming was influenced by 1 of the alternate names of Hades, the Greek god (Pluto is the alternate name of Hades).One of the interesting details about Pluto is that, it truly is in this planet’s honor, that the Disney character ‘Pluto’ along with the element ‘Plutonium’, had been named.As far as the size of Pluto is concerned, it truly is smaller than the size of earth’s moon and is half the width of Ganymede, which is Jupiter’s moon. Pluto has a diameter of about 2340 kilometers as well as a mass of 1.31 x 1022 kilograms. The average distance of Pluto from the sun is around 5,914,000,000 kilometers. It can’t be seen with naked eye and by means of a telescope, it resembles a star.Pluto too has an atmosphere and 3 moons, named, Charon, Nix and Hydra. While Nix and Hydra are smaller in size, Charon is nearly half the size of Pluto. Occasionally, Pluto, along with Charon is treated as a binary method also. Read more on 10 intriguing details about Pluto.Pluto is primarily composed of rock and ice and is brownish yellow in look. Its atmosphere can be a thin layer of gases, like, nitrogen, methane and carbon monoxide. These gases form as Pluto moves closer to the sun and also the gases freeze as it goes farther away from the sun.In accordance with some astronomers, Pluto was as soon as a moon of Neptune. However, the existing orbit of Pluto is elliptical, which brings it closer to the sun than Neptune.Pluto’s orbital period is around 247.7 earth years, which indicates that it takes around 90,410 earth days for Pluto to revolve about the sun as soon as. Given that its discovery in 1930, it has not even revolved once around the sun totally. In the event you calculate its orbital period from 1930, it has yet another 168 years to total its orbit.Yet another truth about Pluto is that it has a very low rotation speed as compared to other planets within the solar technique. As a result, a day on Pluto amounts to 6 days and 9 hours.Read far more on:Is Pluto a PlanetInteresting Facts Concerning the Solar SystemHow Several Planets are ThereFacts About Dwarf PlanetsIt is also contended that Pluto could turn out to be a comet, if it gets closer to the sun, as it contains rock and ice, in a way comparable to comets. Even though, it has lost its planetary status, let us not forget the fact that it is the only ‘planet’ discovered inside the twentieth century. Hope this post is an addition to your expertise about Pluto details and data.

Pluto, named after the Roman God of the Underworld, was discovered for the first time by Clyde W. Tombaugh in 1930. Since then, rigorous studies and photographic plate comparisons have been done for about one year, which led to the designation of Pluto as a planet. That is why, many of us grew up with the textbook lessons that our solar system comprised nine planets, namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Of these, Pluto was the farthest and smallest planet of the solar system.

For many decades, astronomers were unsure regarding the mass of Pluto. Consequently, there was no doubt about Pluto as a planet till 1978. In that year, astronomer James Christy discovered that this small planet has a moon (known as Charon), whose diameter is predicted to be half of Pluto. But, what led to the breakthrough that Pluto is not a planet? This article throws lights on why is Pluto not a planet .

Why is Pluto Not a Planet Anymore?

It is true that Pluto is no longer a planet, but it is categorized under the dwarf planet. This is because, Pluto fails to meet the specific requirements of being a planet. A dwarf planet is defined as any spherical object that fails to clear its neighborhood around its orbit. And for an object to be called a planet, it needs to meet certain characteristic features; it should orbit the sun, should be large enough and have sufficient center of gravity to become spherical, and last but not the least, it should be a dominating body in its orbit. Though Pluto revolves around the sun, it is very small and does not clear its orbit. Know more on facts about dwarf planets.

The identification of Charon is like a milestone in the field of astronomy. With the discovery of Charon that orbits Pluto, astronomers succeeded in determining the actual mass of Pluto. Unlike other planets whose size is much bigger than their moons, the size of Pluto is twice that of Charon. Also, what astronomers found out is that Pluto and Charon are more or less similar to binary planets, which take approximately 6.38 days to complete one revolution around each other. Know more on Pluto’s moon Charon.

As mentioned already, the main reason for declaration of Pluto as a dwarf planet is that it does not clear its neighborhood in the orbit. Other planets have a strong gravitational force that upon interaction with small celestial bodies (comets, asteroids, etc.), they either consume them or sweep them up. In brief, planets have a cleared orbital path, which is not so in case of Pluto. The orbit of Pluto is somewhat untidy, with many other objects around its orbit. Because of this, Pluto is now relegated as a dwarf planet.

Or why is Pluto a dwarf planet? In the latest 2006 publication, the International Astronomical Union (IAU) officially declared that our solar system has eight planets (not nine). However, it is possible to discover a large object in the solar system that qualify the definition of a planet. Also, it can still happen that Pluto gains its mass after crashing with objects and pass the planet-hood status. Until then, we have eight planets in our solar system!

Pluto has always been a topic of interest, being the smallest planet in the solar system, that too, the farthest from the sun. The latest controversy about Pluto is with regard to its planetary status. As per the decision taken at the convention of the International Astronomical Union (IAU) in 2006, Pluto was demoted to the status of a dwarf planet. However, many astrologers still consider it as a planet and the debate regarding its planetary status is still on. Let us take a look at some planet Pluto information, which may be helpful in updating your knowledge about Pluto.

Planet Pluto Facts

We all know that Pluto enjoyed the status of a planet till 2006. It was the ninth planet of the solar system and the most distant one from the sun. During the latter half of the twentieth century, scientists discovered some minor planets, with more mass than Pluto. This led to the formulation of a definition for ‘Planet’, and as per the definition, Pluto was not entitled to be called a planet. So, it was reclassified as a dwarf planet along with other minor planets. It is the second largest dwarf planet in the solar system and the tenth largest body found to be revolving around the Sun in an orbit. The following are some interesting information about planet Pluto.Pluto was discovered in 1930. Researchers named Lowell and William H. Pickering were behind most of the efforts in discovering this planet, but, it was Clyde Tombaugh, who discovered the planet, accidentally.Pluto was named after the Greek god, Hades (the god of the underworld) and ‘Pluto’ is one of the alternate names of Hades.This name was suggested by Venetia Burney, a nine-year old school girl from Oxford in England.Pluto is smaller than the earth’s moon in size and has a diameter of around 2,340 kilometers. Its mass is about 1.31 x 1022 kilograms.Pluto has three natural moons and their names are Charon, Nix and Hydra. Charon is almost half the size of Pluto, but the other two are smaller. Read more on Pluto’s moon charon.Pluto’s atmosphere consists of a thin layer of gases, like, nitrogen, methane and carbon dioxide. When the planet moves closer to the sun, gases are formed and when it moves farther, these gases freeze.Pluto is believed to be composed of rock and ice and is brownish in appearance. It is speculated that 70% of Pluto is composed of rock and the remaining is ice. The surface temperature of Pluto may range between -235 and -210? C.Pluto cannot be seen with naked eye and if you observe it through an amateur telescope, it will be seen as a star. It may take several days of detailed observations to locate Pluto. Only the largest features on its surface can be viewed through the Hubble space telescope.Another interesting planet Pluto information is that Pluto has not been visited by a spacecraft till date. If everything goes right, the spacecraft called ‘New Horizons’ (launched in 2006) should reach it in 2015.The period of orbit for Pluto is estimated to be around 247.7 earth years. In other words, it takes around 90,410 earth days for Pluto to revolve around the Sun once.The rotation speed of Pluto is very low and so, a day on Pluto amounts to earth’s 6 days and 9 hours. It is also noted that Pluto rotates in the opposite direction when compared to most of the other planets.One of the interesting Pluto facts is that it is in its honor, the element plutonium and the Disney character Pluto were named.Read more on: Is Pluto a Planet10 Interesting Facts about PlutoThe above said is only a brief account of planet Pluto information. As there are limitations in access to Pluto, very little is known about it. If you want to know more, you may conduct a detailed study for more facts about Pluto, which is the only ‘planet’ discovered in the twentieth century.

Did you know that a day on Uranus’s poles last for 42 years each? This also means that Uranus takes 82 years to complete one revolution around the Sun. Well, there are many more interesting facts about this planet which almost spins on its sides. Yes, its true; unlike other planets which have a slightly tilted axis, Uranus spins at a 99 degree slope. According to the scientists, a collision with a space object may have changed the slope of its axis.

The Uranus was discovered on the 13th of March 1781, by Sir William Herschel and was named after a Greek God. It is visible to naked eyes, but interestingly, was discovered after the invention of the telescope. Internally the planet is made up of ices of ammonia, water and methane. The Uranus shares the name “ice-giant” with Neptune and is the coldest planet of our Solar System with -224 oC as the minimum temperature.

Let us find out a few more interesting facts about this 7th planet of our Solar System.

Low Density
Uranus is the planet with second lowest density, the first one being Saturn. Its density is 1.27 g/cm3.

Uranus Rings
How many rings does Uranus have? It is now an established fact, that the rings around this planet are 13 in number, and are visible only through the telescope. These are extremely narrow as compared to that of the Saturn and only few kilometers in thickness. Rings made of ice is the specialty of Uranus; though some amount of dust is spread between these rings.

Spectacular View
Although the Uranus doesn’t offer a pleasing view to our naked eyes – just a dull blue color, it is possible to see storms and magnificent bands of clouds when seen through the infrared wavelength of light.

Uranus Moons
Uranus has as many as 27 moons. But these are tiny, and even if we add their total weight it is less than half of the total weight of Triton – Neptune’s largest moon.

Fierce Winds
Uranus has a windy atmosphere. Winds blowing with great speeds of 200 miles per hour, is a common thing on the surface of Uranus.

Green Color
Uranus appears to be green due to the methane gas present in its atmosphere. Photochemical smog is also another reason for the color.

Magnetic Field
The cause behind Uranus’s magnetic field is not clearly known. Geometric center is the source of magnetic field in other planets. It is said that the magnetic field is due to certain substances, found at shallow depths in the planet’s surface.

Brightness of Uranus
Uranus comes under the category of ‘one of the few brightest planets’ seen from the earth.

Voyager 2
Uranus was visited only once, on 24th January, 1986. The spaceship Voyager 2 sent by NASA – came within 81,500 kilometers of Uranus’s atmosphere. After that no other spaceship has been sent to the Uranus.

The only Greek Name – Uranus
Except Uranus, every other planet has a Roman name. It is the only planet with a Greek name.

Fluorescent Cheerio
There is a bright ring known as the “Fluorescent Cheerio” on one of the moons of Uranus’s moon – Umbriel.

The facts which we know about Uranus and the images received by the Voyager 2 have been an important source for studying this planet closely. In the future too, there are no voyages planned for this weird but interesting planet. Let’s hope that, the next voyage to explore more about Uranus is undertaken in the near future.

In 1977, the rings of Uranus were discovered by the astronomical team consisting of Edward W. Dunham, James L. Elliot and Douglas J. Mink. These rings begin at a distance of nearly 38,000 km from the center of Uranus and extend up to 98,000 km. They are thin and only few km in thickness. These rings are not bright, and are composed of water ice with some dark radiation-processed organics. The rings of Uranus are nearly 600 million years old and developed from the collisional fragmentation of a number of moons that existed around the planet. After a collision, the moons broke up into many particles that lasted as narrow and optically dense rings in the zones of maximum stability.

Rings of Uranus

ε Ring
The ε ring is the densest and the brightest ring of the Uranian ring system. It is responsible for about two-thirds of the light reflected by the rings and has a brightness ratio 2.5-3.0 approximately. Out of all Uranus rings, it is the most eccentric ring and hence, has negligible orbital inclination. This ring is very thin and has an estimated thickness of 150 m. The ring is known for its interior and exterior shepherd moons: cordelia and ophelia respectively. The estimated weight of the ring is 1016 kg.

δ Ring
The δ ring is circular and has slight orbital inclination. It shows substantial azimuthal variations in normal optical depth and width. The possible reason is, this ring has an azimuthal wave-like structure, excited by a small moonlet inside it. The ring appears relatively bright and comprises of two components: a narrow optically dense component and a broad inward shoulder with low optical depth.

γ Ring
The γ ring has a zero orbital inclination. It is narrow, optically dense and slightly eccentric. The ring’s width varies from 3.6-4.7 km with a constant optical depth of 3.3 km. Geometrically it is thin like the δ ring and devoid of dust, showing significant azimuthal variations.

η Ring
The η ring has negligible orbital eccentricity and inclination. Similar to the δ ring, it also comprises of two components: a narrow optically dense component and a broad outward shoulder with low optical depth. The ring appears bright which indicates the presence of a sufficient amount of dust in the ring. Like other rings, this ring also shows considerable azimuthal variations in the normal optical depth and width.

α and β Rings
The α and β rings are considered to be the second brightest rings of Uranus. Like the ε ring, these rings show periodic variations in their brightness and width. These rings have sizable orbital eccentricity and non-negligible inclination. The widths of the α and β rings are 4.8-10 km and 6.1-11.4 km, respectively. They are geometrically thin and devoid of dust. The masses of these rings are approximately 5?1015 kg each, nearly half the mass of the ε ring.

Rings 6, 5 and 4
Rings 6, 5 and 4 are the innermost and dimmest of all Uranus rings. They are inclined rings and have large orbital eccentricities. The rings are the narrowest rings of Uranus, measuring about 1.6-2.2 km, 1.9-4.9 km and 2.4-4.4 km width respectively.

λ Ring
The λ ring is a narrow, dull ring located between the ε ring and the shepherd moon Cordelia. The ring was discovered by the Voyager 2 (a spacecraft) in 1986. The λ ring is extremely narrow measuring about 1-2 km, having the equivalent optical depth of 0.1-0.2 km at the wavelength 2.2 μm. Its optical depth shows strong wavelength dependence, which is uncommon for the Uranian ring system.

1986U2R/ζ Ring
In 1986, the Voyager 2 detected a wide and faint sheet of material inbound of the ring 6. It was given a temporary designation of the 1986U2R ring. It had a normal optical depth of 10−3 or less and was located between 37,000 and 39,500 km from the center of Uranus. In late 2003, through the Keck telescope, a broad and dull sheet of material was observed inside the ring 6. The ring was renamed as the ζ ring. However, the position of the ζ ring differs significantly from the observed ring in 1986, and it is located between 37,850 and 41,350 km from the center of the planet.

μ and ν Rings
In 2003-2005, the Hubble Space telescope detected a pair of unknown rings μ and ν, later called as the outer ring system. These rings are broad, dull and17,000 and 3,800 km wide, respectively. They have triangular radial brightness profiles and peak optical depths of 8.5?10−6 and 5.4?10−6 respectively. The μ ring is the outermost of the pair, having twice the distance from the planet as compared to the η ring. Geometrically, the rings are much brighter, which indicates presence of many micrometer-sized dust. The outer rings of Uranus may appear similar to the G and E rings of the planet Saturn. The μ ring is blue in color due to the presence of small dust predominates in it, which are probably made of water ice. On the other hand, the ν ring is slightly red in color.

Uranus is one of the 4 planets in our solar system which has rings. Along with the 1986U2R/ζ and λ rings, there are other extremely dull dust rings in the Uranian ring system. These rings appear bright in forward scattered light, but are invisible during occultations due to negligible optical depth.

The Uranus which is seventh in the series of planets present in our solar system, was discovered on 13th March, 1781 by William Herschel. And this faraway planet took its time to reveal the answer to, “What is Uranus made Of?”, which is explored here in brief. Atmosphere of the Uranus is coldest among other planets and the main components are ammonia, water and methane. The minimum temperature that can be reached by this coldest planet is -224?C.

What is Uranus Made Of?
The density of Uranus is 1.27g/cm3. Total mass of the planet is 14.5 times greater as that of Earth. Owing to the gaseous outer layer, Uranus doesn’t have a hard surface. Let us understand what is Uranus made of, in the following paragraphs.

Composition of Uranus
Uranus is made of three layers; the outer one is gaseous, middle layer is formed of ice, while the innermost layer is hard and rocky. The middle layer forms bulk of this planet and though, it is known as the ice layer, a dense and hot mixture of ammonia, water and other substances are its components. Water clouds present in Uranus form the lower layers of atmosphere, while upper layers contain methane as their main component. The icy mantle is also referred to as water-ammonia ocean by scientists. If we compare the mass of earth and inner layer of Uranus, the latter is just 0.55% of the former. Density at the center of Uranus is 9 g/cm3 while temperature is 5000 K. Atmosphere of Uranus is composed of molecular helium and hydrogen. The helium molar fraction in upper troposphere is 0.15 +/- 0.03. This value is quite close to 0.275 +/- 0.01, the protosolar helium mass fraction. This indicates that, center of Uranus doesn’t have helium settled in it. Cloud structure of the troposphere is said to be complex. Water clouds are present at the place/plane in troposphere where the pressure range is 50-100 bar. Percentage of methane found in the atmosphere is 2.3%. Stratosphere of Uranus contains traces of different types of hydrocarbons. Ultra-violet rays emitted from Sun cause the photolysis of methane, resulting into formation of hydrocarbons. The three-layered model of Uranus presented by scientists is considered as standard. However, different models based on correct observations are also proposed.

Rings of Uranus
The rings of Uranus are 13 in number and composed of dust and other macroscopic particles. Since, the rings are made of material which is dark, their geometric and Bond albedo is 5-6% and 2% respectively. It is difficult to say anything about the chemical composition of the Uranus rings. It is said that the rings might be composed of organic compounds; these organic compounds are darkened by radiations emerging from magnetosphere of Uranus.

Facts About Uranus
The facts about Uranus presented below are mostly those which provide information about structure and composition.The unique color that Uranus possesses, is obtained from methane. Red light absorbed by methane is reflected as blue giving the planet its color.Different layers of Uranus merge or blend into each other seamlessly. These layers are not separated by a clear border.The poles of Uranus are tilted to such an extent, that they almost face the Sun directly.Due to rapid rotation of Uranus, storms (600 km/hr) are formed on it .Images captured by Voyager 2, a spaceship, didn’t show any significant features of the planet Uranus. However, increased weather activity and other signs of seasonal change have been observed in recent years. These changes were also seen by terrestrial observers during the equinox of Uranus.Read more on:Interesting Facts About Planet UranusGreek God UranusUranus is considered as a weird planet of our solar system due to the extremely tilted axis and other interesting information.

“My Very Educated Mother, Just Showed Us the Nine Planets!” This is what I can recall from the treasure chest of my childhood memories, when I started knowing about the solar system. “Mercury, Venus, Earth, Mars, Jupiter, Sa… Hmmm… and I forgot!” It was quite tough for a 5 year old kid to remember the names of all the nine planets in the Solar System. So, my teacher taught me an easy way out with the mnemonic which I have cited above. And then it was easy as piece of cake! Well, that was a tiny part of what I studied in my school days. And I must say that I am really glad that I am putting down this article on Uranus facts and information for all of you, as doing this gives me a great pleasure in reliving that tiny part of my school life. Before I get too much nostalgic, let’s start our journey to the seventh planet of our solar system – Uranus. Whoosh!..

Interesting Uranus Facts

To start off with the Uranus facts for kids, the planet is known to be the third among the largest and fourth among the most massive planets in the Solar System. March 13, 1781 was the day when this huge icy planet was discovered, by an English astronomer named William Herschel. Initially, he took it to be a large comet until it was confirmed to be a planet with the help of more observations and calculations.

Do know which is the coldest planet in the solar system? I always thought it to be Pluto! Why? For obvious reasons, as the planet was the farthest from the Sun. And I was right until Pluto’s name was excluded from the list of the nine planets. So this leaves us with the planet Uranus to be the coldest one having a minimum temperature of -224 ?C. What is interesting to know about the coldness of this Uranus is that it is closer to the Sun than Neptune is. But still it has a colder temperature, in fact, the coldest. This is due to the fact that other planets have cores which have tremendous amount of temperature and they radiate infrared radiations. However, the core of Uranus has cooled down to such as extent that it is not able to radiate much heat, like others do.

Coming to one more of many interesting Uranus facts for kids, this planet is of a faint blue color. The reason? The primary composition of this planet, which is similar to that of Jupiter and Saturn, is of hydrogen and helium. However, it contains more of water, ammonia, methane and traces of hydrocarbons. And the methane which makes the upper atmosphere of the planet tends to absorb the red light from the Sun and give out a pale reflection of blue light thus, the planet is blue in appearance. How much do you know about what is uranus made of? if your answer is, “Not much”, then you must have a look at this link!

To continue the Uranus facts, its rings are what we should discuss about. And you thought that only Saturn had rings? These rings are beautifully bright and look amazing through any telescope. But this is not the only one to have some sets of rings, because even Uranus has them and that too, in the form of a complicated planetary ring system. Extremely dark particles of very petite size (micrometers to a fraction of a meter), make up the rings of Uranus. Till date, scientists have been able to discover 13 of such rings and the brightest of all has been named as the ‘ε ring’. Scientists also claim that the age of the rings is less than that of the planet itself and that they are still young.

Some More Quick Uranus Facts

Find a large pool of water and throw Uranus in it! Well, if you can do that, you will expect it to sink in the water. Thanks to its density – 1.27 g/cm3. It is the second least dense planet after Saturn, which would float if thrown in the pool!

The planet has 27 natural satellites, i.e., moons. One of the interesting facts about the planet Uranus is related to the names of all these moons. They were named after characters in plays written by William Shakespeare.

I wasn’t aware of the fact that Uranus was the first one to be discovered after the invention of the telescope. Most other planets are visible to the naked eyes.

Till now there has been only one visit of the Earthlings to Uranus. It was in the year 1986, in the month of January, when NASA’s spacecraft, Voyager 2 managed to come within 81,000 km of the surface of this third of the four gas giant planets of the Solar System. Thousands of pictures of the planet and its moons were taken, before the spacecraft sped off towards for its next destination. And finally when the pictures came, all what scientists could see was a pale blue, featureless world. So much for a wait of 6 years!

17 hours and 14 minutes equals a day on the Uranus, as that is the time it takes to rotate on its axis. And 84 Earth years is the time taken by this planet to take a full trip around the Sun.

Axis of all other planets have a tilt similar to that of the Sun and that is the reason why they can be viewed as tilted spinning tops on the plane of the Solar System. It is different with this one under discussion. Uranus’ axis lies on its side and has a tilt of 99 degrees. Meaning, the planet rotates on its side. This gives it a look of a ball rolling on its side. Due to this strange but interesting feature, each pole on the planet receives around 42 Earth years of continuous sunlight, followed by the same number of years of darkness.

And as the last point for this session on the Uranus facts, the light reflected from this planet lies within the brightness scale that can be perceived by the humans eyes. So, if you know exactly where to look and if the sky is completely dark, you might be lucky enough to spot this strange planet even with your naked eyes. You could be luckier if you can arrange for a pair of binoculars!
