A magnificent ring system

Saturn is a gas giant composed mostly of hydrogen and helium. It has the lowest density of any planet in our Solar System, with about two-thirds being water.

Saturn's rings are made of countless individually orbiting particles that are primarily water ice; most are smaller than a house.

Saturn's inner rings may be the flattest structures in our Solar System. Their diameter is about 30 million times longer than their two-story height.

Several moons of Saturn are visible, along with Venus, Earth and its moon, and Mars.

Mysterious moons with strange oceans and seas

Saturn's largest moon, Titan, is the only known extraterrestrial world to host rain, rivers, stable lakes and seas, where methane plays the role of water on Earth.

Saturn's moon, Enceladus, has a liquid water ocean beneath its frozen water shell.
