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.

26924 Johnharvey           Discovered 1996 Dec. 30 by R. Tucker at Goodricke-Pigott Observatory.
With his fundamental contributions to solar physics, John Warren Harvey (b. 1940) has advanced the understanding of solar magnetic fields and oscillations. He was largely responsible for the successful implementation of the Kitt Peak Vacuum Tower Telescope, the GONG helioseismology network and the SOLIS instrument.
