Asteroid 2010 AA15 is in a similar but different orbit than main-belt comet P/2010 A2.[3] Using the best-fit short-arc orbital data, it appears as if the closest that comet P/2010 A2 came to asteroid 2010 AA15 is around 0.0155 AU (2,300,000 kilometres (1,400,000 mi)) on November 22, 2009.[3]
2010 AA15 was discovered on January 7, 2010.[1] 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.[1] The asteroid appears to have come to perihelion (closest approach to the Sun) on around January 10, 2010,[1] only a couple days after its discovery.
With an absolute magnitude (H) of 19.2,[1] 2010 AA15 is likely about 600 metres (2,000 ft) in diameter.[2]
