2013 LA2 is a centaur and damocloid on a cometary-like and retrograde orbit from the outer Solar System, suggesting that it is an extinct comet. It was first observed on 1 June 2013 by astronomers with the Pan-STARRS survey at Haleakala Observatory, Hawaii, in the United States.[1] The object measures approximately 1.8 kilometers (1.1 miles) in diameter.[3] It holds the record for having the highest orbital inclination of any known minor planet.
