Ceres

The largest known asteroid, Ceres is 623 miles (1,003 km) in diameter, and orbits roughly 260 million miles (420 million km) from the Sun. Italian astronomer Giuseppe Piazzi discovered Ceres in 1801. Since it was the first asteroid ever discovered, it also carries the designation "1 Ceres." In 2006, astronomers also classified Ceres as a dwarf planet.
