The 16-mile-wide (26-kilometer-wide) crater Insitor is located almost exactly in the center of Kerwan crater on Ceres.

Scientists can compute the chances that a cosmic dart would hit exactly at the bullseye of the largest crater on Ceres by using models of impact frequency as a function of time, combined with the period of time since Kerwans formation. By counting the number of craters within Kerwan and comparing that number to the distribution of craters on Earths moon and other bodies, it is possible to derive an approximate time for Kerwans formation of between 550 and 750 million years ago. The chance that a crater the size of Insitor would be formed at the center of Kerwan over that period is only one in one hundred.

This image of Ceres was obtained by NASAs Dawn spacecraft on September 23, 2015, from an altitude of about 915 miles (1,470 kilometers). Insitor crater is located at 10.7 degrees south latitude, 124.9 degrees east longitude. The crater gets its name from the Roman agricultural deity in charge of the sowing of crops.

NASAs Dawn spacecraft took this image of Hakumyi Crater on Ceres, visible left of center. The crater is named after a Paraguayan, Brazilian and Bolivian spirit said to be helpful in gardening.

Hakumyi, 18 miles (29 kilometers) in diameter, is located about 43 miles (70 kilometers) west of Ernutet Crater. Ernutet is where scientists found evidence of organic material, thanks to Dawns visible and infrared mapping spectrometer.

Evidence for organics was also found at the 4-mile (6.5 kilometer) wide fresh crater on the southern rim of Hakumyi and on the lobe-shaped flow of material that runs into Hakumyi. These two features look relatively young in comparison to the rest of Hakumyi Crater, whose rims and overall shape are subdued. The lobate flow is reminiscent of the Type I flows identified in multiple places at high latitudes on Ceres, and suggests a significant amount of ice near the surface.

Dawn took this image on August 20, 2015, from 915 miles (1,470 kilometers) altitude. The center coordinates of this image are 48.9 degrees north latitude and 27.0 degrees east longitude.

Ceres Haulani Crater, with a diameter of 21 miles (34 kilometers), shows evidence of landslides from its crater rim. Smooth material and a central ridge stand out on its floor. This image was made using data from NASAs Dawn spacecraft when it was in its high-altitude mapping orbit, at a distance of 915 miles (1,470 kilometers) from Ceres.

This enhanced color view allows scientists to gain insight into materials and how they relate to surface morphology. Rays of bluish ejected material are prominent in this image. The color blue in such views has been associated with young features on Ceres.
