Ceres – a dwarf planet in our Solar System
Ceres is a dwarf planet in our solar system. It is a rock-ice body some 590 miles in diameter with a surface area approximately equal to the land area of India or Argentina.
Ceres’s oblateness is inconsistent with an undifferentiated body, which indicates that it consists of a rocky core overlain with an icy mantle. This 100-km-thick mantle (23%–28% of Ceres by mass; 50% by volume)contains 200 million cubic kilometers of water, which is more than the amount of fresh water on Earth.
NASA’s Dawn spacecraft will reach it in February 2015.
The Moon compared to the asteroids and dwarf planets in our solar system – Ceres is farthest left.
Early next year the Dawn Spacecraft should send back images that will render these crude images obsolete.. just as it did with Vesta.
