gas giant
Massive hydrogen sphere
A gas giant is a massive planet composed primarily of hydrogen and helium rather than rock or solid matter.
In our solar system, Jupiter and Saturn are gas giants, while Uranus and Neptune are sometimes distinguished as ice giants.
The term contrasts with terrestrial planets like Earth: Could life exist on a gas giant's moons?
