The moon is named after Remus, twin of the mythological founder of Rome, one of the children of Rhea Silvia raised by a wolf. 87 Sylvia has a low density, which indicates that it is probably a rubble pile asteroid formed when debris from a collision between its parent body and another asteroid re-accreted gravitationally. Thus it is likely that both Remus and Romulus are smaller rubble piles which accreted in orbit around the main body from debris of the same collision. In this case their albedo and density are expected to be similar to Sylvia's. Remus' orbit is"

This would be the first discovery of rings around a moon. The potential discovery was announced in the journal ""Science"" on March 6, 2008. In November 2005 the ""Cassini"" orbiter found that Saturn's magnetosphere is depleted of energetic electrons near Rhea. According to the discovery team, the pattern of depletion is best explained by assuming the electrons are absorbed by solid material in the form of an equatorial disk of particles perhaps several decimeters to approximately"

They may not be stable around Dione and Tethys because those moons are so much closer to Saturn, and therefore have much smaller Hill spheres, or around Titan because of drag from its dense atmosphere. Several suggestions have been made for the possible origin of rings. An impact could have ejected material into orbit; this could have happened as recently as 70 million years ago. A small body could have been disrupted when caught in orbit about Rhea. In either case,"

"satellites orbiting Rhea could have stable orbits. Furthermore, the suspected rings are thought to be narrow, a phenomenon normally associated with shepherd moons. However, targeted images taken by the ""Cassini"" spacecraft failed to detect rings around Rhea. It has also been proposed that Saturn's moon Iapetus had a satellite in the past; this is one of several hypotheses that have been put forward to account for its equatorial ridge. Two natural satellites are known to have small companions at both their and Lagrangian points, sixty degrees ahead and behind the body in its orbit. These companions are called trojan moons,"
