This loss occurred in 2006 when the International Astronomical Union (IAU) set new criteria for planethood. While Pluto was spherical and orbited the Sun, it failed the critical test: it had not gravitationally cleared the neighborhood around its orbit. Pluto orbits within the Kuiper Belt, a crowded zone of icy debris, proving it is just one of many large objects out there.
