* Jupiter: Although primarily composed of hydrogen and helium, Jupiter has a rocky core surrounded by a layer of metallic hydrogen and a thick atmosphere with traces of frozen gases like methane and ammonia.
* Saturn: Similar to Jupiter, Saturn is mostly hydrogen and helium, but also has a rocky core and an atmosphere containing frozen gases like methane and ammonia.
* Uranus: Uranus is composed mainly of ices (water, methane, and ammonia), with a small rocky core. Its atmosphere is primarily hydrogen and helium.
* Neptune: Like Uranus, Neptune is composed mainly of ices, with a small rocky core. Its atmosphere is primarily hydrogen and helium, and it also has traces of frozen gases like methane and ammonia.
It's important to note that these "frozen gases" are not solid ice in the traditional sense. They are actually extremely cold gases that have condensed into liquid or solid states due to the extreme pressure and cold temperatures in the outer solar system.
