'Lonely Mountain' on Dwarf Planet Ceres Shines in Jaw-Dropping Photos

The mountain, with an altitude of 21,120 feet (6,437 meters), is one of many gorgeous features captured in the new images, which Dawn took on Aug. 19. Dawn currently orbits Ceres at an altitude of 915 miles (1,470 kilometers), but in October, the probe will start spiraling down to an orbit just 230 miles (375 km) above the surface. The images show that the "lonely mountain" is not part of any visible mountain range (hence its name).
