113 - What Makes a Planet (feat. Phil Metzger)

In 2006, the IAU voted to define "Planet" in a way that had a profound impact on planetary science, most notably with regards to Pluto. But what is the story behind this decision, and why is it important to the field of exploration? Dr Phil Metzger joins Jake to talk about his new paper covering the very subject, and explains the context behind culture and science's different views on the subject.
