dwarf planet is a planetary-mass object that does not dominate its region of space (as a true or classical planet does) and is not a satellite. That is, it is in direct orbit of the Sun and is massive enough to be plastic – for its gravity to maintain it in a hydrostatically equilibrious shape (usually a spheroid) – but has not cleared the neighborhood around its orbit of other material.The prototype dwarf planet is Pluto. Ceres as seen from the Dawn spacecraft. It is the only dwarf planet in the asteroid belt. Pluto as viewed by New Horizons space probe on July 13, 2015. Eris and its moon Dysnomia viewed by the Hubble Space Telescope. Makemake and its moon viewed by the Hubble Space Telescope. Haumea and its two moons Namaka and Hiʻiaka viewed by the Hubble Space Telescope. The number of dwarf planets in the Solar System is unknown, as determining whether a potential body is a dwarf planet requires close observation. The half-dozen largest candidates have at least one known moon, allo...
