The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury. Saturn has 83 known moons with confirmed orbits as of 2023, not counting the many thousands of moonlets embedded within its dense rings as well as hundreds of potential kilometer-sized distant moons that were briefly seen by telescopes. Seven Saturnian moons are large enough to have collapsed into a relaxed, ellipsoidal shape, though only one or two of those, Titan and possibly Rhea, are currently in hydrostatic equilibrium. Particularly notable among Saturn's moons are Titan, the second-largest moon in the Solar System (after Jupiter's Ganymede), with a nitrogen-rich Earth-like atmosphere and a landscape featuring dry river networks and hydrocarbon lakes, Enceladus, which emits jets of ice from its south-polar region and is covered in a deep layer of snow, and Iapetus, with its contrasting black and white hemispheres. Twenty-four of Saturn's moons are regular satellites; they have prograde orbits not greatly inclined to Saturn's equatorial plane. They include the seven...
