What created this large mountain on asteroid Ceres?
No one is yet sure. As if in anticipation of today being Asteroid Day on Earth, the robotic spacecraft Dawn in orbit around Ceres took the best yet image of an unusually tall mountain on the Asteroid Belt’s largest asteroid. Visible at the top of the image, the exceptional mountain rises about five kilometers up from an area that otherwise appears pretty level.
The image was taken about two weeks ago from about 4,400 kilometers away
