"An image of Occator Crater draped over a digital terrain model provides a 3-D-like perspective view of the impact structure.  Several bright areas can be seen in this crater. The inner part of the crater forms a type of ""crater within a crater"" measuring about 6 miles (10 kilometers) in diameter and 0.3 miles (0.5 miles) in depth, and contains the brightest material on all of Ceres. Occator measures about 60 miles (90 kilometers) wide.  Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA"
