Looking at Tom’s excellent post on Mimas, I can’t help but be drawn to its most prominent feature, the crater Herschel.  It’s almost unbelievable that the impact responsible for that didn’t completely destroy the moon.  Here are some other images of Herschel put up on the Cassini website:

If Earth were to carry a crater of equivalent scale, it would be wider than Canada.

Its appearance similarities to the Star Wars “Death Star” is completely coincidental.  The crater wasn’t discovered until several years after the movie was made.
