Remember when Pluto was a planet? Until very recently, the planetary state of Pluto was an immutable fact that children learned in school.

And it had its place in the papier-mâché models of the solar system.

But in August 2006 it was cruelly degraded to a “dwarf planet” by failing to meet one of the three criteria used by the International Astronomical Union to determine that a celestial body is a planet.
