Observations at many sites in South America have made the discovery that the asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris.
