This scene captured by NASA Dawn spacecraft on Oct. 21, 2016, from Ceres northern hemisphere shows part of the rim of Dantu Crater, at top right. Rao Crater is the largest crater in the bottom left corner of the image. Dawn took this image on Oct. 21, 2016, from its second extended-mission science orbit (XMO2), at a distance of about 920 miles (1,480 kilometers) above the surface. The image resolution is about 460 feet (140 meters) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA21243

This oblique view from NASA's Dawn spacecraft shows Rao Crater (7 miles, 12 kilometers) at center left. Dawn took this image on May 30, 2016, from its low-altitude mapping orbit, at a distance of about 240 miles (385 kilometers) above the surface. The image resolution is 120 feet (35 meters) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA20868
