Mimas

Mimas

Saturn's smallest spherical moon is thought to be composed largely of ice.

Though it is only 250 miles (400km) in diameter, Mimas has a huge 80-mile-wide (130km) impact crater called Herschel, which is named after the moon's discoverer, astronomer William Herschel. Some say this large crater makes Mimas look a bit like the Death Star in the Star Wars films.
