Saturn’s rings and its moon Mimas. Mimas was discovered by William Herschel in 1789. This photo was taken by the Cassini space probe on February 17, 2015, when it was at a distance of approximately 2.5 million km from Mimas.
Mimas is a moon of Saturn that has an average orbital speed of 15km/s. You probably know Mimas because it’s the space object that really looks like the death star from Star Wars. It weighs approximately 3.75 × 10^19 kg and its diameter measures 396km. Also interesting to know is that it’s the smallest known space object that’s rounded in shape because of self-gravitation.
