Ganymede is the largest known moon in the Solar System and also the largest known exoplanet moon, orbiting Jupiter.

Kepler-1625b has the most known moons, with a system of five confirmed moons.

Europa is thought to have a subsurface ocean beneath its icy crust, making it a potential habitable environment.

Titan has a thick atmosphere composed primarily of nitrogen and methane, making it the only moon in the Solar System with a substantial atmosphere.

Europa is tidally locked to Jupiter, meaning that one side of the moon always faces the planet.

Io is the most volcanically active body in the Solar System, with hundreds of active volcanoes.

Saturn is the only planet in the Solar System with a prominent ring system.

Ganymede is the only moon in the Solar System known to have a magnetic field.
