    A dwarf planet is a planetary-mass object that is neither a planet nor a satellite. A dwarf planet as a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitational rather than mechanical forces it has sufficient mass to overcome its internal compressive strength and achieve hydrostatic equilibrium, and is thus an ellipsoid in shape but unlike a planet has not cleared its orbital region of other objects.
