Bad Astronomy Talks about Deimos

The Bad Astronomy blog has a post up about the HiRISE imaging of Deimos with a cool new image of the smaller Martian moon.

HiRISE view of Deimos

From BA:

Deimos is the smaller of the two moons, a lumpy ball 15 x 12 x 10 km in size (Phobos is 27 x 22 x 18). Deimos has incredibly weak gravity; its escape velocity is only about 20 km/hr, so you could throw a baseball right off into space, and biking without taking an unintentional EVA would be difficult.
