Mimas, also designated Saturn I, is a moon of Saturn which was discovered in 1789 by William Herschel. It is named after Mimas, a son of Gaia in Greek mythology.


With a diameter of 396 kilometers (246 mi) it is the smallest astronomical body that is known to still be rounded in shape because of self-gravitation. However, Mimas is not actually in hydrostatic equilibrium for its current rotation. (Source: Wikipedia)

The Cassini spacecraft ended its mission on Sept. 15, 2017.
