A dwarf planet is a body that orbits the Sun and is massive enough for gravity to pull it into a round shape, but which has not cleared other objects from its orbital neighborhood. The category was created by the International Astronomical Union in 2006, the decision that reclassified Pluto. Five are officially recognized: Ceres in the asteroid belt, and Pluto, Eris, Haumea, and Makemake beyond Neptune. Many more candidates are known in the Kuiper Belt, and the true number is likely in the dozens or hundreds.
