what are uranus rings made of

Thank you. The closest ring is 38,000 km away from the center of Uranus and the furthest ring is 98,000 km away. Instead of containing dust, the rings seem to be made up of larger chunks, measuring 0.2 to 20 m across. Can someone please help me on this. Most rings are made of rocks 0.2–20 meters wide. Uranus has two sets of rings: Inner set, and outer set. The majority of the particles are bright, which means they haven't had time to collect dust. This suggests the ring particles get recycled somehow. Uranus rings fall into three groups based on size, location, and composition. However, some rings are optically thin: the broad and faint 1986U2R/ζ, μ and ν rings are made of small dust particles, while the narrow and faint λ ring also contains larger bodies. Scientists think that the rings are at not more than 600 million years old. read more. The inner set composes of 9 rings: Zeta, 6, 5, 4, Alpha, Beta, Eta, Gamma, Delta.They are narrow and dark gray colored. 0 0. δ ring. The narrow main rings. There are the narrow main rings, outermost rings, and the dusty rings. Source: en.wikipedia.org. While the rings themselves are thought to be as old as the solar system, the particles that make up the rings are very young. Nu is reddish and dusty. read more. The outer set composes of 2 rings: Nu and Mu. This sighting is generally considered doubtful, as the rings are quite faint, and in the two following centuries none were noted by other observers. Unlike the rings of Saturn, which are very bright and composed of water ice, the rings of Uranus are relatively dark. ε ring. They made a series of critical new observations about Uranus rings, which were published in The Astronomical Journal. The majority of Uranus's rings are opaque and only a few kilometers wide. William Herschel described a possible ring around Uranus in 1789. The ring’s geometric thickness is estimated to be 150 meters. The ring system contains little dust overall; it consists mostly of large bodies 0.2–20 m in diameter. But some rings are made of very small dust particles. Uranus’ rings consist of 3 major groups. The ε ring is the densest and brightest in the Uranus ring system. There are the narrow main rings, the dusty rings, and the newly discovered outer ring system. I am doing a report and I really need the info. It has a maximum or minimum brightness ratio of 2.5 to 3.0. Older particles have been covered by interplanetary dust, leaving them less reflective.
