The Hubble Space Telescope's Advanced Camera for Surveys studied the asteroid Ceres for a full nine-hour rotational period. The observations represent the most complete view of Ceres, showing that the asteroid has a round shape like Earth and may have a rocky core and a thin crust, also like our planet. Ceres may even have a mantle of water-ice. The features are reflected in this movie of the asteroid's rotational period. Credit: Credit: NASA, ESA, J.Y. Li (University of Maryland) and G. Bacon |
