What is Pandora in astronomy?

Answer 1

Pandora is an inner satellite of Saturn. It was discovered in 1980 from photos taken by the Voyager 1 probe, and was provisionally designated S/1980 S 26. In late 1985 it was officially named after Pandora from Greek mythology. It is also designated as Saturn XVII. Pandora is the outer shepherd satellite of the F Ring. It is more heavily cratered than nearby Prometheus, and has at least two large craters 30 km in diameter. The orbit of Pandora appears to be chaotic, as a consequence of a mean motion resonance with Prometheus. The most appreciable changes in their orbits occur approximately every 6.2 years, when the periapsis of Pandora lines up with the apoapsis of Prometheus and the moons approach to within about 1,400 km. Pandora also has a 3:2 mean-motion resonance with Mimas. From its very low density and relatively high albedo, it seems likely that Pandora is a very porous icy body. There is a lot of uncertainty in these values, however, so this remains to be confirmed.

Answer 2

In astronomy, Pandora is the name of a moon of the planet Saturn. It was discovered in 1980 by the Voyager spacecraft. Pandora is one of the shepherd moons of Saturn's F ring, helping to shape and maintain the ring's structure.
