PLUTOID

Plutoid

A plutoid or ice dwarf is a trans-Neptunian dwarf planet: that is a body orbiting beyond Neptune that is large enough to be rounded in shape. The termĀ plutoid was adopted by the International Astronomical Union working group Committee on Small Bodies Nomenclature, but was rejected by the IAU working group Planetary System Nomenclature. The term plutoid is not widely used by astronomers, though ice dwarf is not uncommon.
