largest Kuiper Belt objects

The following table lists all known Kuiper Belt objects (KBOs) with diameters that exceed or may exceed 1,000 km. Pluto and its moon, Charon, are included because, although they are normally spoken of as a planet and satellite, respectively, both have many features in common with KBOs.
