Prometheus is the Saturn moon that shares the Pandora myth’s name with the Titan who warned Epimetheus.
The moon Prometheus was discovered in 1980 from Voyager 1 images and is one of the shepherd satellites of Saturn’s F ring. Pandora, discovered in the same broad period of Voyager exploration, shepherds the ring from the opposite side. Their paired astronomical names reflect the relationship between the two figures in Greek mythology.
In the myth, Prometheus is the Titan who helps humanity by stealing fire from the gods. He warns his brother Epimetheus not to accept gifts from Zeus, but Epimetheus accepts Pandora. The mythological connection explains why Prometheus and Pandora were chosen for nearby ring-related moons.
Prometheus is irregularly shaped and has a relatively low density. Its gravity can create disturbances in the F ring, including streamer channels and other changing structures. Thus the name links a mythological pair with a real orbital partnership around Saturn.
