This image, taken by NASA's Dawn spacecraft, shows dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was taken on June 18, 2015. A mountain 3 miles (5 kilometers) high, surrounded by relatively smooth terrain, can be seen near the center of the limb. The same feature can be seen in PIA19586.
