Excerpts:
The "shepherd" moons keep Saturn's F-ring in check
The Cassini probe en route to Saturn has spotted two "shepherd" moons which keep one of the planet's rings in check through their gravitational influence.

Prometheus and Pandora stabilise Saturn's narrow, ribbon-like F-ring.

But the moons may have other, chaotic effects on the F-ring - their orbits become unpredictable when they approach each other very closely.

(...)may also be responsible for features that sometimes form in the ring known as clumps and strands.
