Episode description
When is a planet not a planet? When it gets downgraded after 75 years, apparently. But was Pluto’s fate a mistake by the IAU, or an example of science in action? Marcos Huerta joins Antony to talk Kuiper belt objects, the New Horizons probe, and arbitrary astronomical definitions.
