- Titan. Apart from being the second-largest moon in the Solar System, and the largest moon of Saturn, Titan is the only celestial object besides our planet, where stable bodies of surface liquid have been found.
- Rhea. Rhea is the second-largest moon of Saturn after Titan, and overall the ninth-largest moon in the Solar System. It is bigger than the dwarf planets Makemake and Ceres.
- Iapetus. Iapetus is the third largest moon of Saturn and the eleventh-largest moon in the Solar System. It is bigger than the dwarf planets Makemake and Ceres.
- Dione. Dione is one of the largest inner moons of Saturn, and it was discovered in 1684 by Italian astronomer G.D. Cassini. Dione is the fifteenth largest moon in the Solar System, and it has a diameter of around 1,122 km / 697 mi and a radius of 561 km / 348 mi.
- Titan. Titan is the largest of Saturn's moons and the first to be discovered. Titan is the only moon in the solar system known to have a significant atmosphere.
- Dione. Dione is thought to be a dense rocky core surrounded by water-ice. The tidally locked moon is heavily cratered not on its leading side but on its back side.
- Enceladus. Enceladus contains more than 100 geysers at its south pole. Tidal heating causes portions of the icy planet to melt, spewing icy material into space from its "tiger stripes."
- Hyperion. Hyperion was the last of the major satellites to be discovered. Hyperion is a small moon with an irregular appearance. The flattened object resembles an elongated potato rather than a sphere, a form that may have been created when an impact demolished a larger moon long ago.

In Depth. The Voyager and Pioneer flybys of the 1970s and 1980s provided rough sketches of Saturn’s moons. But during its many years in Saturn orbit, NASA’s Cassini spacecraft discovered previously unknown moons, solved mysteries about known ones, studied their interactions with the rings and uncovered new mysteries – including the ...
