The largest of the asteroids by far, Ceres' diameter is nonetheless less than 1,000 km, about a third of the diameter of Pluto.
The relatively bright rise shown in this view of Ceres is Ahuna Mons, a cryovolcano rising nearly five kilometres above the surrounding terrain. This is the only such feature to be found on the asteroid.

Ceres' orbit through the Asteroid Belt takes nearly five years to complete, and during that period it passes from the inner regions of the Belt to its outer edge and back.
