Dwarf Planets

Hide this area Introduction

A dwarf planet is a category of celestial bodies in the solar system defined by the International Astronomical Union (IAU) on August 24, 2006 in Prague.

A dwarf planet is an object which is in orbit around the Sun and has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape but has not "cleared the neighbourhood" around its orbit.
