Mimas [MY-mass] is one of the innermost moons of Saturn. William Herschel discovered the moon on 17 September 1789. The surface is icy and heavily cratered. Mimas has a low density, meaning it probably consists mostly of ice. Because Mimas has such a low temperature of about -200° C (-328°F), the impact features may date back to the time of the moon's creation.

One of the craters, named Herschel, is surprisingly large in comparison to the size of the moon. The crater is 130 kilometers (80 miles) wide, one-third the diameter of Mimas. Herschel is 10 kilometers (6 miles) deep, with a central mountain almost as high as Mount Everest on Earth. This central peak rises 6 kilometers (4 miles) above the crater floor. This impact probably came close to disintegrating the moon. Traces of fracture marks can be seen on the opposite side of Mimas.

Although Mimas is heavily cratered, the cratering is not uniform. Most of the surface is covered with craters greater than 40 kilometers (25 miles) in diameter but in the south polar region, craters greater than 20 kilometers (12 miles) are generally lacking. This suggests that some process removed the larger craters from these areas.

Mimas was named by Herschel for Mimas, the Titan who was slain by Hercules.
