is a sub-kilometer asteroid and binary system, classified as a near-Earth object of Apollo group 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 size ratio of 0.28.
Near-Earth asteroid Although is classified as a near-Earth object, it does not pose any threats. It has never, nor will it ever in the next century, come closer than from Earth or Venus. However, the asteroid would make a good target for a spacecraft flyby, as a flyby to would only require a delta-v of 5.4 km/s.
Moon has one minor-planet moon. It was discovered from lightcurve observations made by Czech astronomer Petr Pravec and collaborators. This moon is approximately in diameter. Its semi-major axis is and its orbital period is 16.4 hours.
