Uranus's internal structure

Videonummer 11930048
Model of the internal structure of the planet Uranus. Uranus is the second most distant planet from the Sun, orbiting at just under 20 times the Earth-Sun distance. It is some 51, 120 kilometres in diameter, just over four times Earth's diameter. It has a thin ring system. The tops of its clouds are largely featureless. Beneath these clouds is a thick atmosphere of hydrogen, helium and methane (light green). Below that is a thick layer of 'ices' (dark green), largely water, ammonia and methane that exist as a hot, dense liquid. At its centre is a rocky core (grey), formed of iron, nickel and silicates. Uranus's greenish colour comes from traces of methane, which absorbs red light.
