Relax, This Moon Isn't a Death Star

By Chris Mills on at

Mimas is a 250-mile-wide moon in orbit around Saturn, mostly non-descript apart from its appearance: it looks creepily, unsettlingly like Darth Vader's Death Star.

This photo was taken by NASA’s Cassini spacecraft 10 years ago, 1.3 million miles away from Mimas. Since then, we’ve learned a lot about Saturn’s little friend: not only does it have a secret identity as Pac-Man, but it is also hiding a frozen lake (or an irregularly shaped core) under that surface, right next to the thermal exhaust port.
