Pandora, the small object orbiting Saturn, is a moon.
Pandora is an inner satellite of Saturn and acts as an outer shepherd of Saturn’s narrow F ring. Its gravitational influence helps confine the ring’s material, working with the nearby moon Prometheus, which shepherds the ring from the inner side.
Voyager 1 images led to Pandora’s discovery in 1980, although it was not immediately recognized as a moon. The International Astronomical Union later approved the name Pandora, taken from the woman in Greek mythology. Pandora is an irregular, potato-shaped body rather than a spherical planet-like world.
The moon is only a few dozen kilometres across and has a very low density, suggesting substantial internal porosity or ice-rich material. It is unrelated to 55 Pandora, which is an asteroid, and to the fictional moon called Pandora in the film Avatar. Those three uses share a name but describe different kinds of objects.
