Which Saturnian moon shares the F-ring shepherd role with Pandora?

Prometheus shares the F-ring shepherd role with Pandora. These two small moons orbit on opposite sides of Saturn’s narrow F ring and help shape its structure through gravity.

Prometheus is the inner shepherd moon, while Pandora is the outer shepherd. Their interactions with ring particles produce waves, streamers, and other changing features observed in spacecraft images. The system is an important example of how small moons can influence a planetary ring.

Prometheus and Pandora were both named after figures from Greek mythology. Prometheus is associated with giving fire to humanity, while Pandora is associated with the jar that released troubles into the world. Their names can be confused because both moons belong to the same ring system and were studied together by Voyager and later missions.
