Examples of use of D-ring
1. A piece of the D ring also has shifted, moving 200km inward towards Saturn.
2. Among the most surprising findings is that parts of Saturn‘s innermost ring – the D ring – have grown dimmer since the Voyager spacecraft flew by the planet in 1'81.
3. The D ring finding was among several Cassini–related discoveries announced on Monday at a meeting of the American Astronomical Society‘s division of planetary sciences in Cambridge, England.
4. First in the line of new discoveries is that parts of the D ring (Saturn‘s innermost ring) have relocated and dimmed.
5. Images show one of the major discrete ring structures in the D ring has changed in brightness and moved inward towards Saturn by as much as 200 kilometers (124 miles). A change over the 25 years since the NASA Voyager spacecraft flybys indicates very short evolutionary lifetimes in the D ring and is of great interest to ring scientists who have been hoping that Cassini would yield information about ring ages and lifetimes.
