The Surface of Mimas
The surface of Mimas is pockmarked with craters. In that respect Mimas is very much like Callisto
. The largest crater is what gives Mimas its characteristic resemblance to the Death Star. This crater represents perhaps the largest impact that a small body such as Mimas could sustain without shattering. The crater is about 135 km (90 miles) across, which is about the width of Lake Michigan. Perhaps a collision such as this is what caused an older moon to break apart and form Epimetheus
