Noun
Definition: Any astronomical body which has achieved hydrostatic equilibrium (which is the shape a body of water would take, as opposed to a small Solar System body), orbits the Sun (as opposed to a moon), and has not “cleared its neighbourhood” of competing bodies (as opposed to a classical planet or, in IAU usage, as opposed to a planet).
