That’s no moon—oh, wait. It actually is. In honor of Star Wars Day, NASA is celebrating a moon near Saturn’s orbit that looks suspiciously like The Death Star. Officially dubbed the The Mimas, the moon has a 400 km diameter crater that gives it that distinct “Galactic Empire Killing machine” feel. As the innermost of Saturn’s moons, Mimas orbits the planet in just 23 hours. And while we wish that Mimas was filled with Stormtroopers and TIE fighters, NASA says that the moon only consists of “water ice.” But, for our sake, maybe its better that way.
