Wikipedia definition
1. Ceres (dwarf planet)Ceres, formally 1 Ceres, is the only dwarf planet—and the largest asteroid—in the inner Solar System. It is a rock–ice body some 950 km (590 mi) in diameter, and though the smallest identified dwarf planet, it constitutes a third of the mass of the asteroid belt. Discovered on 1 January 1801 by Giuseppe Piazzi, it was the first asteroid to be identified, though it was classified as a planet at the time.
