Saturn Moons

As of June 8, 2023, Saturn has 146 moons in its orbit. The moons range in size from larger than the planet Mercury – the giant moon Titan – to as small as a sports arena. The small moon Enceladus has a global ocean under a thick, icy shell. Scientists have identified both moons as high-priority science destinations for future deep space missions.

Saturn's moons shape, contribute to, and also collect material from Saturn's rings and magnetosphere.
