Prometheus is the Greek mythological figure whose name is shared by Pandora’s companion moon near Saturn’s F Ring.
Saturn’s moon Prometheus is one of the two small shepherd satellites associated with the F Ring; the other is Pandora. In Greek mythology, Prometheus is the Titan who steals fire from the gods and gives it to humanity. Zeus responds by arranging a punishment that includes Pandora’s arrival among mortals.
The astronomical naming creates a direct mythological pairing: Prometheus orbits inside Saturn’s F Ring, while Pandora orbits outside it. Their gravitational interactions help maintain and structure the narrow ring. Prometheus was discovered in Voyager 1 images in 1980, while Pandora was identified in the same general period from Voyager observations. The moons are physically small, but their gravitational effects are important for understanding Saturn’s ring dynamics.
