Ep. 125: A Zoo of Extrasolar Planets

February 2nd, 2009

Episode 142 of 460 episodes

Dreaming up new planets is a favorite pastime of science fiction writers, but the universe often has them beat – coming with planets in place and forms that we had quite thought to imagine. Today we know of 228 stars orbiting alien stars, and in this episode we will look at the diversity of these worlds, from Mushy Lava covered planets to Icy Giants to the hottest of hot Jupiters.
