The minor planet discovered in 1858 and named Pandora is 55 Pandora.
55 Pandora is a large main-belt asteroid discovered by George Mary Searle on September 10, 1858, at the Albany Observatory in New York. It received the name Pandora after the figure from Greek mythology. Its designation combines the discovery order among numbered minor planets with its mythological name.
The asteroid is not the same object as Saturn’s moon Pandora. The moon was discovered much later, in 1980, by Voyager 1 images and is a small shepherd satellite associated with Saturn’s F ring. This distinction matters because astronomical objects can share mythological names across different categories. 55 Pandora orbits the Sun in the main asteroid belt between Mars and Jupiter, while Saturn’s Pandora orbits a planet in the outer Solar System.
