A Look at the Inside of Neptune

The Giant planets do not have the same kind of layers inside that the Earth-like planets do. The history of the giant planets was so different that they formed with much more gas and ice on the inside.

Motions in the interior of Neptune help form the magnetosphere of Neptune. Heat generated within Neptune helps form the unusual winds of the atmosphere.
