What Does Neptune Look Like Inside?

Neptune is the eighth and farthest planet from the Sun in our solar system. It is an ice giant, meaning that it is made up of a large amount of "icy" materials, such as water, methane, and ammonia. However, these materials are not actually made of ice in the same way that we think of ice on Earth. They are in a hot, dense fluid state.
