Moons of Saturn

The planet Saturn has 274 moons with confirmed and stable orbits. Sixty-three of these have officially been named, after Titans, Giants, or minor Greek or Roman gods. Most of these moons are very small: 248 of the above total are less than  in diameter. Saturn also has many moonlets, extremely tiny particles within Saturn's rings that orbit the planet.

 Confirmed moons 
The moons of Saturn that were announced by 2018 are listed here by orbital period (or semi-major axis), from shortest to longest. Moons massive enough for their surfaces to have collapsed into a spheroid are highlighted in bold, while the irregular moons are listed in red, orange and gray background.

Unconfirmed moons
The following objects (observed by Cassini) have not been confirmed as solid bodies. It is not yet clear if these are real satellites or merely persistent clumps within the F Ring.

Hypothetical moons
Two moons were claimed to be discovered by different astronomers but never seen again. Both moons were said to orbit between Titan and Hyperion.
 Chiron which was supposedly sighted by Hermann Goldschmidt in 1861, but never observed by anyone else.
 Themis was allegedly discovered in 1905 by astronomer William Pickering, but never seen again. Nevertheless, it was included in numerous almanacs and astronomy books until the 1960s.
