Шаблон:Mp 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]
Near-Earth asteroid
Although Шаблон:Mp 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 Шаблон:Convert from Earth or Venus.[1] However, the asteroid would make a good target for a spacecraft flyby, as a flyby to Шаблон:Mp would only require a delta-v of 5.4 km/s.[3]
Moon
Шаблон:Mp has one minor-planet moon, Шаблон:Mp. It was discovered from lightcurve observations[3] made by Czech astronomer Petr Pravec and collaborators.[2] This moon is approximately Шаблон:Convert in diameter. Its semi-major axis is Шаблон:Convert and its orbital period is 16.4 hours.[2]
