It's actually a planetoid. In the same way a meteoroid is not an asteroid, a planetoid is not just a small planet. A planet must not , for the most part, share its orbit with other large celestial objects. Pluto was never a planet (Earth word, Earth definition), its un-planet-like characteristics were just undetectable at the time it was given a name.
