A Look at what Uranus' Atmosphere is Made of

Unlike Jupiter and Saturn, where the atmosphere is made the simple molecules hydrogen and helium, the atmosphere of Uranus is cold enough to contain more of a complex molecule called methane.

Uranus' atmosphere originally formed from complex molecules and ice, rather than the simple molecules of which Jupiter and Saturn formed.
