Edit Pluto: planet? Not a planet? Sort of a planet?

Title

Brief

In this episode of the PEZ podcast, we dive into the big question: Is Pluto a planet, a dwarf planet, or something in between? Aimed at curious 3rd–5th graders, the episode tells the story of Pluto from its discovery in 1930 by Clyde Tombaugh, to its clever naming by 11‑year‑old Venetia Burney, to the 2006 decision that reclassified it as a dwarf planet.

We explain the three official rules for being a planet in clear, kid‑friendly language and show which rule Pluto fails, using fun comparisons and simple examples. Listeners will learn about Pluto’s strange, stretched‑out orbit in the Kuiper Belt, its five moons (including its giant partner Charon), and what NASA’s New Horizons spacecraft discovered when it flew past Pluto in 2015—icy mountains, a giant heart‑shaped plain, a thin changing atmosphere, and possible ice volcanoes.

Throughout the episode, we share both sides of the ongoing "Is Pluto a planet?" debate so kids can think like scientists and decide for themselves. By the end, listeners will understand not just what Pluto is like, but how scientific ideas change over time as we make new discoveries.
