PIA21396: Dawn XMO2 Image 31

Dawn XMO2 Image 31


The low angle of illumination brings this pair of nested craters near Ceres' south pole into sharp relief. The larger exterior crater is 53 miles (85 kilometers) in diameter and more than 1.6 miles (2.5 kilometers) deep.

The inner crater displays a central peak, which rises above the darker shadow regions surrounding it. Similar central structures are found in mid-sized craters across the solar system. The central structure in the larger, exterior crater was likely obliterated by the impact of the inner crater. A complex, lobe-shape, flow-like feature, possibly a landslide triggered by an impact on the crater's rim, is visible on the southwest wall of the larger crater. Such flows are common within Ceres' craters.

This picture was obtained by the Dawn spacecraft on October 24, 2016, from an altitude of about 930 miles (1500 kilometers).

The image is located at 73 degrees south latitude, 175 degrees east longitude.
