Pandora is the name of one of Saturn’s small moons discovered in Voyager 1 images. It was found in 1980 by photographs returned by the spacecraft during its flyby of Saturn.
The moon is a shepherd satellite of Saturn’s narrow F ring. Its gravity helps influence the ring’s structure, together with the nearby moon Prometheus. Pandora is the outer shepherd, while Prometheus orbits closer to Saturn.
Pandora’s diameter is only about 81 kilometres, making it far smaller than Saturn’s major moons such as Titan and Rhea. Its irregular shape and bright surface were studied using spacecraft images and later observations.
The moon’s name comes from the figure in Greek mythology. Astronomical naming creates a common source of confusion: “Pandora” can mean a mythological woman, an asteroid, or Saturn’s moon. The Voyager discovery identifies this answer specifically as the satellite.
