jupiter’s rings are made of material from?
dust
the neptunian rings contain a large quantity of micrometer-sized dust: the dust fraction by cross-section area is between 20% and 70%. in this respect they are similar to the rings of jupiter, in which the dust fraction is 50%–100%, and are very different from the rings of saturn and uranus, which contain little dust (less than 0.1%). the particles in neptune's rings are made from a dark material; probably a mixture of ice with radiation-processed organics. the rings are reddish in color, and their geometrical (0.05) and bond (0.01–0.02) albedos are similar to those of the uranian rings' particles and the inner neptunian moons. the rings are generally optically thin (transparent); their normal optical depths do not exceed 0.1. as a whole, the neptunian rings resemble those of jupiter; both systems consist of faint, narrow, dusty ringlets and even fainter broad dusty rings.

rings of jupiter





























the planet jupiter has a system of rings known as the rings of jupiter or the jovian ring system. it was the third ring system to be discovered in the solar system, after those of saturn and uranus. it was first observed in 1979 by the "voyager 1" space probe and thoroughly investigated in the 1990s by the "galileo" orbiter. it has also been observed by the hubble space telescope and from earth for several years. ground-based observation of the rings requires the largest available telescopes.
