Шаблон:Short description

Шаблон:Use dmy dates Шаблон:Infobox planet Шаблон:Mp (also written 2010 XC15) is an Aten near-Earth asteroid and potentially hazardous object that spends most of its time inside of the orbit of Earth.[1] It has an observation arc of 10 years and an Uncertainty Parameter of 1.[1] It was discovered on 5 December 2010 by the Catalina Sky Survey at an apparent magnitude of 17.5 using a Шаблон:Convert Schmidt.[2]

Based on an absolute magnitude of 21.4,[1] the asteroid has an estimated diameter of about Шаблон:Convert.[3] Шаблон:Mp is noted for a close approach to Earth on 27 December 1976 at a distance of about Шаблон:Convert.[4][5] In November 2011 with an observation arc of 40 days, the JPL Small-Body Database showed that the uncertainty region of the asteroid during the 1976 close approach could result in a pass anywhere from 0.001 AU to 0.018 AU from Earth.[4] During the 1976 close approach the asteroid reached about apparent magnitude 14.[6]

The asteroid will pass Шаблон:Convert from Earth on 27 December 2022,[4][5] allowing a refinement to the known trajectory. The uncertainty region in 2013 suggested that the asteroid could have passed inside the orbit of the Moon in 1907, but is now known to have passed about Шаблон:Convert from Earth in 1907.[4]
