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.
