10199 Chariklo, a centaur, was the first minor planet discovered to have rings. It has two rings, perhaps due to a collision that caused a chain of debris to orbit it. The rings were discovered when astronomers observed Chariklo passing in front of the star UCAC4 248-108672 on June 3, 2013 from seven locations in South America.
The rings would initially have been much more massive (≈1,000 times) and broader than at present; material in the outer portions of the rings would have coalesced into the innermost moons of Saturn (those closest to Saturn), out to Tethys, also explaining the lack of rocky material in the composition of most of these moons.

A stellar occultation in 2013 [7] [22] revealed that Chariklo has two rings with radii 386 and 400 km and widths of about 6.9 km and 0.12 km respectively. [10] The rings are approximately 14 km apart. [10] This makes Chariklo the smallest known object to have rings.
The planet has a bright and extensive system of rings, composed mainly of ice particles, with a smaller amount of rocky debris and dust. At least 146 moons [33] orbit the planet, of which 63 are officially named; these do not include the hundreds of moonlets in the rings.
The rings of Chariklo are a set of two narrow rings around the minor planet 10199 Chariklo. Chariklo, with a diameter of about 250 kilometres (160 mi), is the second-smallest celestial object with confirmed rings (with 2060 Chiron being the smallest [ 1 ] ) and the fifth ringed celestial object discovered in the Solar System , after the gas ...
Planet f has an unusually low density, and might have rings or an extended atmosphere. [94] ... 1000: K: 0.88: 5190: unknown: 5:
The main ring was discovered in 1979 by the Voyager 1 space probe [1] and the system was more thoroughly investigated in the 1990s by the Galileo orbiter. [2] The main ring has also been observed by the Hubble Space Telescope and from Earth for several years. [3] Ground-based observation of the rings requires the largest available telescopes. [4]
J1407b is a substellar object, either a free-floating planet or brown dwarf, with a massive circumplanetary disk or ring system.It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days.
