I’ll give you a clue, it totally ruined Alderaan’s day. It then became a lazy plot device in future films.
Pretty cool huh? Its actually one of Saturn’s moons called Mimas, and astronomers think it was hit by an object with just enough force to leave this huge crater, but not totally destroy the moon itself. Lunatics think it was made by aliens on purpose in order to… well I’m not sure, neither are the lunatics. They’re wrong though; they’re called lunatics for a reason.
Its actually thought to be the smallest round body in our Solar System, at around 400 km in diameter (bodies with enough mass become rounded as they spin due to the strength of their own gravity). So it’s even the right size to be an Imperial Space Station
Saturn has loads of moons, 62 as of today, but there may be more (smaller) moons still to be discovered. I’m hoping the next one’s going to be named Endor.
In case you’ve still not got it, it’s the freakin Death Star! You know, from Star Wars… ‘It’s a trap!’
