Enceladus is one of the smallest of Saturn's moons that is spherical in shape—only Mimas is smaller [53] —yet is the only small Saturnian moon that is currently endogenously active, and the smallest known body in the Solar System that is geologically active today. [56]
Aegaeon is the smallest known moon of Saturn outside of the rings and has an extremely elongated shape, measuring 1.4 km × 0.5 km × 0.4 km (0.87 mi × 0.31 mi × 0.25 mi) in size. [9] Measurements of its mass show that Aegaeon has a very low density, likely due to a highly porous and icy interior structure. [5]
This particular moon is one of the smallest moons of Saturn that has been directly imaged. [4] S/2009 S 1 is located about 650 km (400 mi) interior to the edge of the B ring, corresponding to a radial distance of 116,914 ± 17 km (72,647 ± 11 mi) from the center of Saturn. The moonlet protrudes 150 m (500 ft) above the B ring plane, which has ...
A deep ocean exists beneath the icy, cratered surface of Saturn’s moon Mimas, according to a new analysis of data from NASA’s Cassini mission. One of Saturn’s smallest moons has a secret ...
Saturn’s moon Enceladus may have all the ingredients necessary to host life, according to a new study based on data from Nasa’s Cassini spacecraft mission.. The spacecraft ended its mission in ...
Explore all 63 of Saturn's verified moons, along with their names and discovery dates. Other moons await official confirmation of their discovery.
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
Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn.With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded in shape due to its own gravity.
