What is the approximate diameter of Saturn’s moon Pandora?

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

Pandora is an irregular, small satellite orbiting Saturn near the planet’s F ring. Because it is not spherical, astronomers describe its size using dimensions rather than a single perfect diameter. Common reference measurements give it dimensions of about 104 by 81 by 64 kilometres, making 81 kilometres a useful approximate diameter for its intermediate axis.

Voyager 1 discovered Pandora in 1980. The moon was initially identified in images from the spacecraft’s Saturn encounter and later named for the mythological Pandora. Its orbit places it just outside the F ring, while Prometheus orbits on the other side. Together, the two moons act as shepherds that help confine and structure the ring.

Pandora’s surface appears cratered and irregular, and its low density suggests a porous interior. Numerical values can vary slightly between sources because irregular bodies are measured along multiple axes, so the question’s approximate wording matters.
