Earth Co-orbital Asteroid 2002 AA29

Asteroid 2002 AA29 is one of three known examples of horseshoe orbit behaviour. The asteroid is co-orbital with Earth; the only substantial difference in orbital parameters being a 10.7 degree inclination. From time to time, 2002 AA29 leaves the horseshoe behaviour and enters a quasi-satellite relationship with Earth (Connors et al. [1]), the next instance being approximately 2580 AD. Using the SWIFT simulation suite running on the Swinburne supercomputer this project investigates the orbital behaviour of 2002 AA29, in particular the quasi-satellite phase. The investigations confirm the presence of quasi-satellite behaviour and discount the possibility of resonances with Jupiter causing the transition.
