Pluto was reclassified as a dwarf or minor planet in 2006 by the IAU because it failed to meet one of three criteria agreed on as characteristics of a true planet: it must be in solar orbit (which would exclude moons), it must be in hydrostatic equilibrium (or a rounded shape, which might eliminate many small, irregular-shaped asteroids), and it must have cleared a significant fraction of its orbit. Pluto failed to qualify under this last stipulation.

Pluto is classified as a dwarf planet because it has not cleared its neighboring region of other debris, one of the criteria necessary for a celestial body to be considered a full-fledged planet. Additionally, its size and characteristics are more similar to other dwarf planets in the Kuiper Belt rather than the eight recognized planets in our solar system.
