A dwarf planet is a planetary-mass object that does not dominate its region of space (as a true or classical planet does) and is not a satellite.That is, it is in direct orbit of the Sun and is massive enough to be plastic – for its gravity to maintain it in a hydrostatically equilibrious shape (usually a spheroid) – but has not cleared the neighborhood of its orbit of similar objects.
