What asteroid number belongs to 55 Pandora, discovered in 1858?

The story behind the answer

The asteroid named Pandora has the number 55.

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 was the 55th asteroid to receive a permanent number, which is why its formal designation begins with “55.” The name refers to Pandora of Greek mythology.

The asteroid orbits the Sun in the main asteroid belt between Mars and Jupiter. It is classified as an S-type asteroid, meaning its surface is generally associated with stony, silicate-rich material. Astronomers have studied its brightness changes to learn about its rotation and shape.

55 Pandora should not be confused with Saturn’s moon Pandora. The two objects share a mythological name but are entirely different: one is a rocky asteroid orbiting the Sun, while the other is a small icy moon orbiting Saturn.
