That's no moon, but in this case, it is. But it has an uncanny resemblance to an armored battleship we loved:
That's Saturn's moon Mimas, and Cassini spacecraft took this photo during a flyby. Its most noticeable feature is a gaping crater named Herschel. And with that crater staring out from its surface, the moon looks familiar, especially for the Star Wars fan. But don't worry, you won't find Grand Moff Tarkin there, and it won't shoot lasers either.
