Extrasolar planet

Definitions

(Noun) An Exodwarf planet. A celestial body that orbits a star or stellar remnant, other than the sun (b) with a mass below that needed for nuclear fusion at its core but sufficient to give it a mostly round shape, that (c) has not "cleared the neighborhood" of its own orbit so as to have more than the total mass of the objects crossing its orbit plus the mass needed to avoid an additional orbit caused by another body around a point in space called the “barycenter” (like Pluto and Charon which are comparable in size and orbit each other, rather than just being a moon orbiting a planet) and (d) is not a satellite.
