An Overview of Uranus' Interior

The Giant planets do not have the same kind of structure inside that the terrestrial planets do. Their evolution was quite different than that of the terrestrial planets, and they have much more gas and ice inside.

Uranus's interior composition is primarily that of methane ice.

Motions in the interior of Uranus contribute to the formation of the magnetosphere of Uranus. Heat generated within Uranus contributes to the unusual motions of the atmosphere.
