Mimas (pronounced MY muss or MEE muss, adjective Mimantean) looks somewhat like a bull’s eye if viewed from a certain angle.(Or the Death Star if your a Star Wars Fan) The feature that causes this is the huge 140-kilometer-wide (88-mile) Herschel Crater, which is one-third the diameter of Mimas. If the object striking Mimas had been larger or been moving faster, Mimas would probably have been “disrupted” into pieces that might have collapsed back into a new moon or might have scattered into another ring of Saturn. The walls of Herschel Crater are approximately 5 kilometers (3 miles) high, parts of the floor are approximately 10 kilometers (6 miles) deep, and the central peak towers are almost 6 kilometers (4 miles) above the floor of the crater. A comparable crater on Earth would be 4,000 kilometers (2,500 miles) in diameter.
