Episode 159 - A Proposal for the Geologic Definition of Planet, Interview with Kirby Runyon

In 2006, the International Astronomical Union sparked an uproar and furious debate among scientists and non-scientists alike when they voted for a definition of the word, planet. Numerous proposals since that time have been made for the definition of that term. Eleven years later, a new proposal has gotten a lot of media attention and in this episode, we discuss that new proposed definition. This is closer to a friendly debate style because the host of this podcast and the guest have different points of view on this issue.
