Saturn has many moons. There are as many as 30 large moons and many smaller sattleites.

Saturn's Moons
Twenty-three of Saturn's moons are regular satellites, with prograde orbits that are not greatly inclined with respect to Saturn's equatorial plane. In addition to the seven major satellites, an additional four moons are small trojans that share an orbit with a larger moon, and two more are mutually co-orbital moons. Finally, two moons are known to orbit within gaps in Saturn's rings. The regular satellites are traditionally named after Titans or other figures associated with the mythological Saturn.
Saturn, the sixth planet from the Sun, is home to a vast array of intriguing and unique worlds. From the cloud-shrouded surface of Titan to crater-riddled Phoebe, each of Saturn's moons tells another piece of the story surrounding the Saturn system

Christiaan Huygens discovered the first known moon of Saturn. The year was 1655 and the moon is Titan. Giovanni Domenico Cassini made the next four discoveries: Iapetus (1671), Rhea (1672), Dione (1684), and Tethys (1684). Mimas and Enceladus were both discovered by William Herschel in 1789. The next two discoveries came at intervals of 50 or more years - Hyperion (1848) and Phoebe (1898).

As telescopic resolving power increased through the 19th century, Saturn's family of known moons grew. In 1966 Epimetheus and Janus were discovered. By the time Cassini-Huygens was launched in 1997, Saturn's moon count had reached 18. The number of known moons soon increased with high-resolution imaging techniques used on ground-based telescopes. Cassini discovered four more moons after its arrival at Saturn and may find even more during its mission.

Each of Saturn's moons bears a unique story. Two of the moons orbit within gaps in the main rings. Some, such as Prometheus and Pandora, interact with ring material, shepherding the ring in its orbit. Some small moons are trapped in the same orbits as Tethys or Dione. Janus and Epimetheus occasionally pass close to each other, causing them to periodically exchange orbits.
