Summary

Description
English: NASA's Hubble Space Telescope colour image of Ceres, the largest object in the asteroid belt. 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")
Français : Image couleur de Cérès, le plus gros corps de la ceinture d'astéroïdes, prise par le télescope spatial Hubble de la NASA. Les astronomes ont affiné la résolution de l'image à environs 18km par pixel, et ont amélioré le contraste afin de faire ressortir les détails de la surface de Cérès, surface qui absorbe en moyenne 91% de la lumière qu'elle reçoit du soleil. (traduction de la description originale de la Nasa) (Distance à la Terre: 1.64 UA, Diamètre angulaire: 0.798")
