The third largest planet

The solar system is made up of the sun, eight planets, satellites, and asteroids and meteoroids, among other celestial bodies. There are eight planets in our solar system.

Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water , ammonia , and methane in a supercritical phase of matter , which in astronomy is called 'ice' or volatiles. It has a marked axial tilt of This means that in an Earth-year orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness. Uranus has the third-largest diameter and fourth-largest mass among the Solar System's planets. Based on current models, inside its volatile mantle layer is a rocky core, and surrounding it is a thick hydrogen and helium atmosphere.

The third largest planet

When viewed through Earth-based telescopes, Uranus looks like a tiny blue green disk. Uranus, however, looks tiny only because it is so far away from Earth. Uranus has a diameter of about 32, miles 51, kilometers. This is about four times the diameter of Earth. In fact, Uranus is the third largest planet in the solar system. These are massive planets that consist mostly of flowing matter.

Space Sci. The Universe in the Classroom. Retrieved 29 May Angular diameter. Retrieved 22 August This extended corona is a unique feature of Uranus. The rings are probably quite young; the dynamics considerations indicate that they did not form with Uranus. Orbital period sidereal. Archived from the original on 29 March The extreme pressure and temperature deep within Uranus may break up the methane molecules, with the carbon atoms condensing into crystals of diamond that rain down through the mantle like hailstones. Archived from the original on 11 February Some small clouds live for hours; at least one southern cloud may have persisted since the Voyager 2 flyby. The first consideration of any particular event, or remarkable incident, seems to be its chronology: if in any future age it should be asked, when this last-found Planet was discovered? The object was soon universally accepted as a new planet.

Atmosphere: The atmosphere of holds hydrogen 83 percent , helium 15 percent , and methane 2 percent. Methane is what gives Uranus its blue-green color.

Archived from the original on 26 July In , Voyager 2 found that the visible southern hemisphere of Uranus can be subdivided into two regions: a bright polar cap and dark equatorial bands. Archived from the original on 9 July I have not yet seen any coma or tail to it. Berlin astronomer Johann Elert Bode described Herschel's discovery as "a moving star that can be deemed a hitherto unknown planet-like object circulating beyond the orbit of Saturn".
