From cosmic VIP to the solar system’s most famous "space potato," Pluto’s journey has been a wild ride. Ever wonder why our favorite ninth planet suddenly got the boot?

In this episode of Brain Blast, your hosts Jordan and Alex dive into the biggest space scandal of 2006: the demotion of Pluto. We break down the official IAU rules that redefined what it means to be a planet and explain the one specific requirement that Pluto just couldn’t meet. From its messy neighborhood in the Kuiper Belt to the discovery of its "twin" Eris, we explore why the solar system is a lot more crowded than we once thought.

We also discuss:

• The Three Rules: What a celestial body needs to join the "Planet Club."
• The Dwarf Planet Squad: Meeting Pluto’s new friends like Ceres and Makemake.
• A Heart of Ice: Why the 2015 New Horizons mission proved Pluto is still a star in our eyes.
