The region shown here is located between 13° and 51° north latitude and 182° and 228° east longitude. The image has been projected onto a globe of Ceres, which accounts for the small notch of black at upper right.
OpNav9 is the ninth and final set of Dawn images of Ceres taken primarily for navigation purposes.
Ceres is covered in countless small, young craters, but none are larger than 175 miles (280 kilometres) in diameter. To scientists, this is a huge mystery, given that the dwarf planet must have been hit by numerous large asteroids during its 4.5 billion-year lifetime. Where did all the large craters go?
Chariklo is the largest confirmed centaur, a minor planet orbiting the Sun between Saturn and Uranus. In 2014, two rings were discovered around Chariklo. Soon after, scientists discovered that rings likely exist around another centaur, Chiron, but the origin of these rings remained a mystery — until now.
