Saturn has the most moons of any planet in the solar system, with more than 140 known as of 2023. Many of these are small satellites that orbit far from Saturn. The largest moons orbit close to the planet and were discovered telescopically before the 20th century. The largest moon, Titan, even has an atmosphere and is the only solar system moon to have one.
More small moons were discovered by the Voyager probes when they flew by Saturn in 1980 and 1981. Many of the small moons were discovered by surveys that sought to discover such bodies.
The earliest satellites discovered were named for the Titans of Greek mythology. More recently discovered satellites have been given names of giants and spirits from legends of the Norse, the Inuit, and the Gauls. The moons of Saturn are listed below in order of increasing distance from the planet, with the year of their discovery, orbital period in days, and diameter in kilometers.
