A dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. That is, it is in direct orbit of a star, and is massive enough for its gravity to compress it into a hydrostatically equilibrious (nearly round) shape, but has not gravitationally "cleared the neighborhood" of material around its orbit.
