That's no moon... It's Pac-Man!

That Herschel crater was the reason why Mimas was nicknamed “the death star”

Interesting, maybe the ejecta from the crater absorbs more heath during the day and thus the surface remains warmer during the night?

Not being an astronomer, my first guess was that the warmer area might be at a higher elevation than the sort-of circular area between it and the crater, and catches more sunlight. Or else there is a density difference.

“Nice stealthing, Darth – it looks just like a moon, as long as they don’t check it out in infrarred.” :slight_smile:

If one squints a little, one can see the vague shape of a ghost about to be swallowed by Pac-Man. :slight_smile:
