Titan
Saturn's largest natural satellite has long been of great interest to scientists. With rivers and lakes of ethane and methane, Titan is the only moon in the Sol System with a dense atmosphere.

Rhea
Made mainly of rock and ice, Rhea is commonly referred to as a "dirty snowball" due to its composition.

Tethys
Tethys is predominantly made of water ice, which gives it a density much lower than other celestial objects its size.

Dione
Strangely, this tidally locked moon features numerous impact craters on its trailing hemisphere, leading scientists to speculate that heavy bombardment from objects once spun Dione 180 degrees.

Iapetus
Tidally locked to Saturn, Iapetus is unusual because of its "two-tone" coloration. The side facing Saturn is constantly shrouded in shadow while the more distant side is illuminated.
