An annotated picture of Saturn 's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. 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 ...
The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups. Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in hydrostatic equilibrium, including Titan, the second

Enceladus is the sixth-largest moon of Saturn and the 19th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [ 5 ] about a tenth of that of Saturn 's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
Rhea ( / ˈriː.ə /) is the second-largest moon of Saturn and the ninth-largest moon in the Solar System, with a surface area that is comparable to the area of Australia. It is the smallest body in the Solar System for which precise measurements have confirmed a shape consistent with hydrostatic equilibrium.
The large craters Engelier and Gerin are near the bottom. Iapetus ( / aɪˈæpətəs /) is the outermost of Saturn's large moons. With an estimated diameter of 1,469 km (913 mi), it is the third-largest moon of Saturn and the eleventh-largest in the Solar System. [a] Named after the Titan Iapetus, the moon was discovered in 1671 by Giovanni ...
Temperature. 93 K (−180 C) [12] Apparent magnitude. 14.1 [13] Hyperion / haɪˈpɪəriən /, also known as Saturn VII, is the eighth-largest moon of Saturn. It distinguished by its highly irregular shape, chaotic rotation, low density, and its unusual sponge-like appearance. It was the first non- rounded moon to be discovered.
Dione (moon) Dione ( / daɪˈoʊni / ), also designated Saturn IV, is the fourth-largest moon of Saturn. With a mean diameter of 1,123 km and a density of about 1.48 g/cm 3, Dione is composed of an icy mantle and crust overlying a silicate rocky core, with rock and water ice roughly equal in mass. Its trailing hemisphere is marked by large ...
