Mimas is among the innermost moons of Saturn, orbiting at a distance of approximately 185 000 km. It is 392 km in diameter. Mimas' largest crater is named after the human who first discovered it; Herschel's crater. The giant crater is about 130 km wide and 10 km deep - The impact which created it must have nearly destroyed the moon. The Herschel crater has a central mountain around 15 kilometers in height, which is a relic from the impact. The moon in generally heavily cratered.
