Ceres's north polar region shows far more cratering than the equatorial region, with the eastern equatorial region in particular comparatively lightly cratered. The overall size frequency of craters of between twenty and a hundred kilometres (10–60mi) is consistent with their having originated in the Late Heavy Bombardment, with craters outside the ancient polar regions likely erased by early cryovolcanism.
The northern polar area of Ceres displays a greater number of craters than its equatorial region, especially in the eastern part. The distribution of craters between 20 and 100 kilometers in diameter is consistent with their origin during the Late Heavy Bombardment period, while those outside the ancient polar regions were likely destroyed by early cryovolcanic processes.
