This side-perspective view of Ceres' mysterious mountain Ahuna Mons was made with images from NASA's Dawn spacecraft. Dawn took these images from its low-altitude mapping orbit, 240 miles (385 kilometers) above the surface, in December 2015. The resolution of the component images is 120 feet (35 meters) per pixel. A 3-D (anaglyph) view is also available.

This mountain is about 3 miles (5 kilometers) high on its steepest side. Its average overall height is 2.5 miles (4 kilometers). These figures are slightly lower than what scientists estimated from Dawn's higher orbits because researchers now have a better sense of Ceres' topography.

The diameter of the mountain is about 12 miles (20 kilometers). Researchers are exploring the processes that could have led to this feature's formation.

Background Info:

Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science.
