Ice giant

Astrophysical Concepts
Planets and Dwarf Planets

An ice giant is a type of giant planet composed mainly of elements heavier than hydrogen and helium, including oxygen, carbon, nitrogen, and sulfur. Uranus and Neptune are the Solar System's two ice giants. They are distinct from the hydrogen and helium dominated gas giants Jupiter and Saturn. Ice giants lack well-defined solid surfaces and are primarily made of gases and liquids, with water mainly occurring as supercritical fluid inside them.

Solar System members: Uranus and Neptune
Surface: No well-defined solid surface
Hydrogen and helium: About 20% by mass
