Interactions With Rings
A faint dust ring is present around the region occupied by the orbits of Janus and Epimetheus, as revealed by images taken in forward-scattered light by the Cassini spacecraft in 2006. The ring has a radial extent of about 5000 km. Its source is particles blasted off the moons' surfaces by meteoroid impacts, which then form a diffuse ring around their orbital paths.
Along with Ephimetheus, Janus maintains the sharp edge of the A Ring by a 7:6 orbital resonance.

Famous quotes containing the words interactions with, interactions and/or rings:
“In our interactions with people, a benevolent hypocrisy is frequently required—acting as though we do not see through the motives of their actions.”
—Friedrich Nietzsche (1844–1900)
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
“If a man do not erect in this age his own tomb ere he dies, he shall live no longer in monument than the bell rings and the widow weeps.”
—William Shakespeare (1564–1616)
