What's the difference between meteorites, comets, asteroids, and the other joyful rocks of space?

SPACE ROCKS was an educational short film I made at Beakus in 2015, commissioned by the Royal Observatory Greenwich, as a video ressource for secondary school teachers. In an effort to explain the scientific subject in a playful way, the characters were created with plasticine, then animated with 2D digital animation. Full credits here. It was showcased on various animation blogs (Catsuka, Animated Short Films), and on the European Space Agency channel.
