The Phoebe ring, Saturn’s largest and faintest ring, lies far beyond the planet’s well-known main rings. It is primarily sourced by collisions with Saturn’s largest irregular satellite Phoebe, perhaps through stochastic macroscopic collisions, or through more steady micrometeoroid bombardment. The ring was discovered with the Spitzer Space Telescope at 24 lm and has a normal optical depth of � 2 � 10 � 8

Small particles dominate Saturn’s Phoebe ring to surprisingly large distances
Saturn’s faint outermost ring, discovered in 2009 (ref. 1), is probably formed by particles ejected from the distant moon Phoebe. The ring was detected between distances of 128 and 207 Saturn radiiExpand
Radial profiles of the Phoebe ring: A vast debris disk around Saturn
Abstract We present observations at optical wavelengths with the Cassini Spacecraft’s Imaging Science System of the Phoebe ring, a vast debris disk around Saturn that seems to be collisionallyExpand

Cladistical analysis of the Jovian and Saturnian satellite systems.
TLDR
This work performs the first cladistical study of objects in a planetary science context, using the orbital, physical and compositional characteristics of satellites to classify the objects in the Jovian and Saturnian systems. Expand
Fundamental limits from chaos on instability time predictions in compact planetary systems
Instabilities in compact planetary systems are generically driven by chaotic dynamics. This implies that an instability time measured through direct N-body integration is not exact, but ratherExpand

Saturn's largest ring
TLDR
It is reported that Saturn has an enormous ring associated with its outer moon Phoebe, extending from at least 128RS to 207RS (Saturn’s radius RS is 60,330 km); Dynamical considerations argue that these ring particles span the Saturnian system from the main rings to the edges of interplanetary space.

Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
TLDR
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings.

The formation of Jupiter's faint rings
TLDR
Observations by the Galileo spacecraft and the Keck telescope showed that Jupiter's outermost (gossamer) ring is actually two rings circumscribed by the orbits of the small satellites Amalthea and Thebe, suggesting that faint rings may accompany all small inner satellites of the other jovian planets.
