This is an image of the planet Uranus taken by the spacecraft Voyager 2 in 1986.

Uranus is composed primarily of rock and various ices, with about 85% hydrogen, 15% helium and traces of methane (in contrast to Jupiter and Saturn which are almost entirely hydrogen). Uranus (like Neptune) is very much similar to the cores of Jupiter and Saturn without the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather that its material is more or less uniformly distributed. Uranus' cyan color is due to the absorption of red light by atmospheric methane.
