Doomed Moon

I haven’t done one of these for a while.

This is Phobos: one of Mars’s two moons, from Astronomy Picture of the Day, 28/10/12. Phobos definitely resembles a potato in this view. Its orbit is so close to Mars that it will eventually be broken up by tidal forces and the remnants smeared into a ring around the planet.
