The asteroid named Pandora is designated 55 Pandora.
55 Pandora is a main-belt asteroid named after Pandora, the first woman in Greek mythology. Its number, 55, reflects the order in which it received a permanent minor-planet designation, rather than a mythological detail about Pandora herself.
The asteroid was discovered by George Mary Searle at the Dudley Observatory in Albany, New York, in 1858. It is classified as an S-type asteroid, meaning its surface is broadly associated with stony, silicate-rich material. Like other main-belt asteroids, it orbits the Sun between the orbits of Mars and Jupiter.
The name can be confused with Pandora, one of Saturn’s moons, but these are different astronomical objects. 55 Pandora is an asteroid orbiting the Sun, while Saturn’s Pandora is a small natural satellite orbiting a planet. The number 55 is therefore the key identifier for the asteroid in astronomical catalogs.
