Asteroid 55 Pandora was named after the Greek mythological figure.
55 Pandora is a large main-belt asteroid discovered by the American astronomer George Mary Searle on September 10, 1858. It was the 55th minor planet to receive a permanent number, and its name follows the astronomical tradition of assigning mythological names to many asteroids.
The asteroid is classified as an S-type asteroid, meaning its surface is broadly stony rather than dominated by carbon-rich material. It travels around the Sun in the main asteroid belt between Mars and Jupiter. Like other numbered minor planets, it is identified by both its number and its name, with the number helping distinguish it from similarly named objects.
55 Pandora is unrelated to the fictional moon in Avatar and to the 1929 film. Those works borrow the mythological name, while the asteroid is an independently named astronomical body.
