For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

| David Hartley (1705-1757) was an English physician and philosopher who attempted to explain how thought processes occur. His major work, Observations on Man, His Frame, His Duty and His Expectations, is important in the history of psychology for suggesting that body and mind function in concert. |
