Small moons have too little gravity to pull themselves into spherical shape. Meet the tiny moons of Mars, moons orbiting asteroids, Saturn’s diverse moons (big and small), and gear up for the first visit to Pluto’s moons.

Unfortunately Phobos-Grunt failed after launch in November 2011 (shortly after this video was made) when rocket failures left it stranded in low Earth orbit.
