Dwarf planet
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body in direct orbit of the Sun that is massive enough that its shape is controlled by gravitational rather than mechanical forces (and thus an ellipsoid in shape), but has not cleared its neighboring region of planetesimals.
