Cassini’s tour of Saturn’s remarkable system of 31 moons took the probe past one of the ringed planet’s natural wonders: Mimas. The 250 mile wide satellite suffered a catastrophic impact that opened a wound one third of its diameter and nearly split the moon in half. Today, Mimas bears a striking resemblance to the Star Wars’ Death Star, which wrecked havoc on planets using its laser-focusing dish. In place of the laser dish, Mimas carries a crater peak the size of Mount Everest.
