What is Pandora’s companion shepherd moon of Saturn’s F ring called?

Pandora’s companion shepherd moon of Saturn’s F ring is called Prometheus.

Prometheus and Pandora are small moons that orbit on opposite sides of Saturn’s narrow F ring. Their gravity helps confine the ring material and contributes to the ring’s changing strands, channels, and kinks. Prometheus is the inner shepherd, while Pandora is the outer shepherd.

The name is mythologically appropriate because Prometheus and Pandora are connected in ancient Greek stories. Prometheus is associated with giving fire to humanity, while Pandora is associated with the jar that releases troubles into the world. The International Astronomical Union uses mythological names for many Saturnian satellites.

Prometheus was discovered in images from Voyager 1 in 1980, although a faint object photographed earlier had not initially been recognized as the same moon. The moon is irregularly shaped and much smaller than Saturn’s major satellites such as Titan and Rhea.
