Medium-sized Moons of Saturn
Saturn has
moons. Many of those are tiny chunks of rock or ice only a few kilometers (miles) across. One of Saturn's moons, Titan, is much larger than the rest and is amongst the largest moons in our entire Solar System.
Midway in size between Titan and the many tiny moonlets are several medium-sized moons. The image on this page shows the mid-sized moons of Saturn. They
are, in order from largest to smallest: Rhea, Iapetus, Dione, Tethys, Enceladus,
Mimas, Hyperion, Phoebe, Janus, Prometheus, Epimetheus and Pandora. The picture also shows Earth's Moon for size comparison.
