(provisional designation ) is a sub-kilometer asteroid and binary system, classified as 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.
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 0.1abbr=onNaNabbr=on 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.[6]
has one minor-planet moon, . It was discovered from lightcurve observations made by Czech astronomer Petr Pravec and collaborators. This moon is approximately 200m (700feet) in diameter. Its semi-major axis is 1.6km (01miles) and its orbital period is 16.4 hours.
