Pandora is the fourth of Saturn's satellites (moons).
It was discovered by S. Collins and others as late as
1980 because of its small size. It was actually discovered
when studying photographs from the Voyager probe.
It has a mass of 0.0013 x 1020 kg, and spans
114 km x 84 km x 62 km. Its mean density is
420 kg/m3, and it has a visual geometric
albedo of 0.9, i.e. quite reflective. It orbits
Saturn with a period of approximately 0.63 Earth days,
at a distance of 141,700 km.
