Hyperion is a really weird moon

Phil Plait over on Bad Astronomer has a lovely selection of the best pictures from Cassini’s 10 years at Saturn.

By far my favourite is the, well, frankly bizarre moon Hyperion. It looks like a well-used oasis sponge. It also has a chaotic rotation, and is the only moon in the system that isn’t tidally locked to it’s planet.

Have a look at Phil’s other selections here.
