Pluto and the Planetary Pandemonium

Pluto and the Planetary Pandemonium

It’s a scientific controversy of planetary proportions! Is Pluto a planet, or not? You decide, after we present two sides of an epic astronomy argument. Back in 2006, the International Astronomer’s Union voted on a definition of the word “planet” that excluded Pluto and other newly dubbed “dwarf planets” from planethood status. Astronomers - and everybody else - quickly chose sides. We dive deep into the debate and learn that Pluto’s not the only Space Object Formerly Known As A Planet. Then we’ll ask you to weigh in with your opinion, and see if you can find “consensus” on what should be called a planet. Featuring planetary astronomer Kirby Runyon. We have a present for your birthday!! We’ll be doing birthday shoutouts for our Patreon members, beginning next month. Want to hear a message on the podcast just for your special day?
