NASA’s Cassini spacecraft has made its final close approach to Saturn’s moon Mimas. At closest approach, Cassini passed 25,620 miles (41,230 kilometers) from Mimas. All future observations of Mimas will be from more than twice this distance.
This incredible image is one of the highest resolution views ever captured of the icy moon and shows the countless craters on it’s surface. The surface area of Mimas is slightly less than the land area of Spain.
Discovered in 1789 by William Herschel, Mimas is named after Mimas, a son of Gaia in Greek mythology. The moon has a diameter of 396 kilometres (246 mi) and is the smallest astronomical body that is known to be rounded in shape because of self-gravitation.
