Pluto, Ceres, Charon and Xena Planets? Hogwash! There's only four in our solar system: Jupiter, Saturn, Uranus and Neptune, then there's the inner five planetoids Mercury, Venus, the Earth Moon double system and Mars, scores of asteroids, the transuranians and comets, basta!
I would say that the brown dwarf that brings death and destruction every 28 million years or so is the only other body to go for full planet status
