Dwarf planet asteroid 1 Ceres

Dwarf planet  asteroid 1 Ceres

Fig. 12.6 . A Hubble Space Telescope image of 1 Ceres, the largest object in the asteroid belt and the first object discovered there. The round shape led to its classification in 2006 as a dwarf planet, and suggested that its interior is layered, with a rocky core, icy mantle and thin, dusty outer crust. Ceres is approximately 950 kilometers across. The differences between lighter and darker regions could be impact features or simply due to a variation in surface material. (Courtesy of NASA/ESA/J.
