Abstract:

A review will be given of the history of the quasi-satellite (QS) trajectory in the Newtonian potential of the solar system, together with the adiabatic invariant governing its motion. This will be followed by a discussion of the fascinating motion of asteroid 2002 AA29, and the relationship of QS motion to the classical horseshoe trajectory. Finally, a new result of the QS form in a logarithmic (galaxy) potential will be described.
