NW of Occator

NW of Occator
NW of Occator Dawn took this picture on Feb. 16 (eight days after the picture above) at an altitude of 240 miles (385 kilometers). It shows a region northwest of Occator Crater, site of the famous bright region (which may become one of the most popular tourist destinations on Ceres). (You can locate this area in the upper right of the mosaic shown last month.) Compare the number and size of craters in this scene with those in the older scene above showing an area of the same size. There are fewer craters here, because the material ejected from the impact that excavated Occator resurfaced the area nearby, erasing the craters that had formed earlier. Because Occator is relatively young (perhaps 80 million years old), there has not been enough time for as many new craters to form as in most other areas on Ceres, including the one shown in the previous picture, that have been exposed to pelting from interplanetary debris for much longer. Full image and caption.
