Ep. 324: Sun Grazers

December 9th, 2013

Episode 357 of 460 episodes

Comets can spend billions of years out in the Oort Cloud, and then a few brief moments of terror orbiting the Sun. These are the sun grazers. Some survive their journey, and flare up to become the brightest comets in history. Others won't survive their first, and only encounter with the Sun.
