Quick Summary

A plutoid is a type of dwarf planet that orbits the Sun beyond Neptune. These celestial bodies are large enough for their own gravity to make them spherical, but they have not cleared their orbital neighborhood of other objects. Pluto, Eris, Makemake, and Haumea are examples of plutoids. Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU) because it did not meet the criteria for a planet, specifically that it had not cleared its orbital path. Plutoids are found in the Kuiper belt, a region of icy bodies beyond Neptune.123456
