Ringed Chariklo
Ringed Chariklo Chariklo is the largest Centaur, an icy world in the realm between asteroids and comets. In 2013, it was discovered to have not one, but two, rings. Chariklo is about 250 km or so in diameter. Its inner ring is at 391 kilometers from the center of Chariklo and is 7 kilometers wide. Its outer ring is at 405 kilometers and is 3 kilometers wide. The gap between the rings is 8 kilometers wide. © Don Davis
