Английская Википедия:2010 AA15
Шаблон:Mp is a sub-kilometer asteroid from the inner asteroid belt, that has a similar but different orbit than main-belt comet P/2010 A2.[1] During January 2010, it had been observed for two weeks by the Mount Lemmon Survey, but has since become a lost asteroid. Шаблон:As of the object has not been recovered.[2]
Description
Using the best-fit short-arc orbital data, it appears as if the closest that comet Шаблон:Mp came to asteroid Шаблон:Mp is around 0.0155 AU (Шаблон:Convert) on 22 November 2009.[1]
This asteroid was discovered on 7 January 2010.[3] Since it has only been observed over a fifteen-day arc of its 3.5 year orbit, details of the exact orbit still need further refining for easy recovery of this object in the distant future.[3] The asteroid appears to have come to perihelion (closest approach to the Sun) on around 10 January 2010,[3] only a couple days after its discovery.
Based on an absolute magnitude of 19.2,[3] and an assumed albedo of 0.24 and 0.05, Шаблон:Mp is likely to measure Шаблон:Convert and Шаблон:Convert in diameter for a stony and carbonaceous composition, respectively.[4]
