Saturn’s moon discovered by Voyager 1 in 1980 is Pandora.
Voyager 1 photographed Pandora on 23 October 1980 during its historic Saturn encounter. Scientists initially gave the object the provisional designation S/1980 S 26 before the International Astronomical Union approved the name Pandora, after the woman of Greek mythology.
Pandora is a small inner moon of Saturn, measuring roughly 81 kilometres across at its longest dimension. It acts as an outer shepherd satellite of Saturn’s narrow F ring, working with the moon Prometheus to help constrain and shape the ring’s material. Its irregular, heavily cratered surface also suggests that it has experienced numerous impacts.
Pandora is sometimes confused with Prometheus because the two moons orbit close to the F ring and are both named from Greek mythology. Prometheus is the inner shepherd; Pandora is the outer shepherd. The Cassini spacecraft later made much closer observations of both moons.
