Mimas
moon of Saturn · the one with the giant crater
8.62 AU from Earth
A ball of ice 396 km across with one enormous crater, Herschel, 130 km wide: about a third of the moon's own width. Its walls rise about 5 km and a peak 6 km high stands in the middle, which is why Mimas looks like the Death Star from Star Wars.
- 396 km across · Herschel is 130 km wide
- Herschel is turned away from the Sun; it is lit for half of each orbit
Numbers that change with time are from 8 November 2026.
