Concerned about the safety of the Cassini orbiter when it pierces the ring plane during its orbital tour, we explored the orbital histories and reaccretion of circumplanetary particles across inner regions of the Saturnian system. Our goal is to find locales just exterior to the rings that might be depleted dynamically of orbital debris. Particles were followed until they impacted a moon, entered the main ring, or traveled well beyond Hyperion's orbit.
Particles typically collide with satellites in about a hundred years.
A few particles are trapped along stable horseshoe and tadpole orbits.
