In 2006, the International Astronomical Union (IAU) created the category of dwarf planets to which Pluto was added. But why was Pluto demoted from being a planet? This video explores the three requirements for a planet and why Pluto doesn't meet all of them. Viva la Pluto.

I believe I was a bit rash when saying that Pluto used to be a planet because scientists haven't been able to figure out what the definition should be. Upon Eris, Haumea, and Makemake's discoveries, the IAU was actually very quick to redefine what makes a planet based on the newfound information.
