Kronos the Planet Eater

Stars have a voracious appetite, gobbling up most of the stuff in their immediate neighborhood, leaving just a few scraps to make planets. Sometimes, though, even the planets do not escape the stellar maw. In this episode of Walkabout, the astroquarks discuss a neat observation that shows a star likely gobbled several rocky worlds at some point in its past. Plus, help NASA name a Kuiper Belt Object, and find out the link between the planet eater and Greek mythology in this episode's trivia.
