That’s no moon!

Actually wait, yes it is. It’s Mimas, Saturn’s 7th biggest moon. The bit that looks like the lasar is the enormous crater Herschel (named for John Herschel, who discovered Mimas in 1789.)

Mimas is 396 km in diameter, which is about half the diameter of Earth’s moon.

May the 4th be with you!
