List of possible dwarf planets
It is estimated that there may be 200 dwarf planets in the Kuiper belt of the outer Solar System [1] and possibly more than 10,000 in the region beyond. [2] The International Astronomical Union (IAU) has accepted four: Pluto , Eris , Haumea , and Makemake , as well as Ceres in the inner Solar System.

At present, the International Astronomical Union classifies five objects as dwarf planets : Ceres , Pluto , Eris , Haumea , and Makemake , though dozens of others are thought likely to be classified as such in the future. The qualifying feature of dwarf planets is that they must "have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium ( near-spherical shape )." [1] [2] [3] Those dwarf planets lying beyond the orbit of Neptune are termed " plutoids ", after Pluto. Except for Pluto and Ceres, observations are insufficient for direct determination. However, based on present knowledge of how icy bodies gravitationally relax into equilibrium shapes, there are currently about 73 candidates amongst the population of trans-Neptunian objects (TNOs). [4] It is estimated that there are around 200 dwarf planets in the Kuiper belt and up to 2000 in the region beyond. [4] The first trans-Neptunian object discovered since Pluto that is a solid dwarf planet candidate is (15874) 1996 TL 66 , and is estimated by the Spitzer Space Telescope to be about 575 km in diameter.
