Uranus is the seventh planet from the sun in our solar system.

Extracts from this document...



Uranus is the seventh planet from the sun in our solar system. This huge, icy planet is covered with clouds and is encircled by a belt of 11 rings and 18 moons. Uranus’ blue colour is caused by the methane in its atmosphere; this molecule absorbs red light.

Rotational Axis:

Uranus’ rotational axis is strongly tilted on its side (97.9*). Instead of rotating with its axis roughly perpendicular to the plane of its orbit (like all the other planets in our Solar System), Uranus rotates on its side (along its orbital path).  This tipped rotational axis gives rise to extreme seasons on Uranus.


Uranus is about 31,690 miles (51,118 km) in diameter.  This is about 4 times the diameter of the Earth.  This gas giant is the third-largest planet in our Solar System

Uranus’s Orbit And Distance From the Sun:

Uranus is over 19 times as far from he Sun as the Earth is; it averages 19.18 A.U.


The mean temperature on the surface of Uranus’s cloud layer is –350*F (59 K)> Uranus radiates very little heat in comparison with the other gas giants, Jupiter, Saturn and Neptune.

Planetary Composition And Atmosphere:

Uranus is a frozen, gaseous planet with a molten core.  Uranus’s atmosphere consists of 83% hydrogen, 15% helium and 2% methane.


Uranus has a belt of 11 faint, narrow rings composed of rock and dust.  They circle Uranus in very elliptical orbits.  These rings are only a fraction of the size of Saturn’s rings, and were only discovered in 1977.


 Uranus has 5 large moons (2 were discovered by Wm.

Planetary Composition And Atmosphere:

Uranus is a frozen, gaseous planet.  The planet is shrouded in an icy cloud layer (made up of frozen methane, ethane, and acetylene) circling this planet at 185 mph

(300 kph.) . Uranus’s icy atmosphere consists of 83% hydrogen, 15% helium and 2% methane.  The outer layers of the atmosphere are the coldest; temperature and pressure rise under the cloud layer.  

Partially-solid Layers:

Beneath the atmosphere, thee are a liquid layer of hydrogen and helium.  As depth increases, this layer becomes more viscous, and then partly solid.  This layer may be composed of compressed water with ammonia and methane.


Uranus has a molten core about 10,500 miles (17,00 Km) in diameter and about 12,500*F (6927*C).  This core may have a mass five times greater than the mass of the Earth.

Spacecraft Visits:

NASA’S Voyager 2, whose closest approach was on, has visited Uranus

24th January 1986.
