[edit] Summary

Description
English: NASA's Hubble Space Telescope color image of Ceres, the largest Main Belt asteroid. Astronomers optimized spatial resolution to about 18 km per pixel, enhancing the contrast in these images to bring out features on Ceres' surface, that are both brighter and darker than the average which absorbs 91% of sunlight falling on it. (Original description by NASA) (Earth Distance: 1.64 AU and Angular diameter: 0.798")
