Mountain on Ceres. Composite created with data from NASA's Dawn spacecraft, showing a conical mountainous feature on the surface of Ceres. Ceres is a minor planet, the largest object in the asteroid belt, and lies between the orbits of Mars and Jupiter. Vertical data has been exaggerated by a factor of 5 to better to illustrate the crater's topography. The mountain is more than six kilometres high, with bright streaks down one side. Dawn was launched on 27 September 2007 on a mission to study Ceres and the asteroid Vesta, the two largest bodies in the asteroid belt. It will provide data on their composition, formation and the early history of the solar system. This three-dimensional terrain model is based on images taken during orbits at altitudes of 13, 600 kilometres and 5, 100 kilometres.
