What is the diameter of Saturn’s moon Pandora, approximately?

Saturn’s moon Pandora has an approximate diameter of 81 kilometers.

Pandora is a small, irregular satellite with dimensions of roughly 104 by 81 by 64 kilometers, so its commonly quoted mean diameter is about 81 kilometers. Because the moon is not spherical, a single diameter is an approximation rather than a complete description of its shape.

Voyager 1 discovered Pandora in 1980, and later observations by the Cassini spacecraft revealed more about its surface and orbital role. Pandora’s low density and irregular form are typical of many small outer satellites. Its orbit just beyond Saturn’s F ring allows it to act as one of that ring’s shepherd moons.

The figure is sometimes confused with Pandora’s longest dimension, which is about 104 kilometers. Those are not contradictory measurements: the moon is elongated, so its three principal dimensions differ. Astronomical summaries usually state the approximate diameter while detailed sources provide all three axes.
