10199 Chariklo /ˈkærəkloʊ/ is the largest confirmed centaur, a class of minor planet in the outer Solar System. It orbits the Sun between Saturn and Uranus, grazing the orbit of Uranus. On 26 March 2014, astronomers announced the discovery of two rings (nicknamed Oiapoque and Chuí after the rivers that define Brazil's borders)[22] around Chariklo by observing a stellar occultation,[23][24] making it the first minor planet known to have rings.[25][26]

A photometric study in 2001 was unable to find a definite period of rotation.[27] Infrared observations of Chariklo indicate the presence of water ice,[28] which may in fact be located in its rings.[7]
