Dwarf Planets are bodies in the Solar System. To be considered a dwarf planet a body must:- 1. * orbit the sun and not be a satellite of any smaller body. 2. * have a gravitational field strong enough to give it a roughly sperical shape. 3. * not have cleared out other bodies orbiting in its field. There are currently five known dwarf planets in the Solar system: * Ceres * Eris * Pluto (Initially a full planet, demoted in August 2006 by a vote by astromoners.) * Haumea * Makemake * Sedna may be a dwarf planet.
