Pandora, Saturn's moon, acts as a shepherd satellite for which planetary ring?

Pandora, Saturn's moon, acts as a shepherd satellite for Saturn's F ring.

Pandora travels just outside the F ring, while the moon Prometheus orbits just inside it. Their combined gravitational effects help confine and shape the narrow, braided ring. For that reason, astronomers call Pandora and Prometheus shepherd satellites.

Pandora is an irregular, heavily cratered moon only a few dozen kilometres across. Its role is gravitational rather than luminous: it does not create the ring, but its orbit influences the distribution and structure of the ring's icy particles.

The name can cause confusion because Pandora is also the woman in a famous Greek myth. Saturn's moon was named for that mythological figure. It is also distinct from the much larger moon Titan and from Saturn's broad, bright A and B rings.
