Dwarf planet [SEP] Introduction
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. The prototype dwarf planet is Pluto. The interest of dwarf planets to planetary geologists is that, being possibly differentiated and geologically active bodies, they may display planetary geology, an expectation borne out by the 2015 "New Horizons" mission to Pluto.
