The
moons of Saturn are numerous and diverse, ranging from tiny
moonlets less than 1 kilometer across to the enormous
Titan, which is larger than the planet
Mercury.
Saturn has 62
moons with confirmed orbits, 53 of which have names and only 13 of which have diameters larger than 50 kilometers. Seven Saturnian moons are large enough to be ellipsoidal in shape, though only two of those, Titan and
Rhea, are currently in
hydrostatic equilibrium, as well as dense
rings with complex orbital motions of their own. Particularly notable among Saturn's moons are Titan, the second-
largest moon (after Jupiter's
Ganymede) in the Solar System, with a nitrogen-rich Earth-like atmosphere and a landscape including
hydrocarbon lakes and dry river networks; and
Enceladus, which is seemingly similar in chemical makeup to comets, emits jets of gas and dust and may harbor liquid water under its south pole region.
