(88710) 2001 SL9 (
provisional designation 2001 SL9) is a sub-kilometer asteroid and binary system, classified as near-Earth object of Apollo group[1] discovered by NEAT at Palomar Observatory on 18 September 2001. It measures approximately 960 meters in diameter, while its 2001-discovered minor-planet moon has an estimated diameter of 200 meters based on a secondary to primary mean-diameter ration of 0.28.[2]
