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.

5548 Thosharriot           Discovered 1980 Oct. 3 by Z. Vavrova at Klet.
Thomas Harriot (1560-1621) is recognized as having made the first use of a telescope to record a celestial object with his drawing of the moon from Syon House, near London, on 1609 July 26 (O.S.), several months before Galileo. Better known as a mathematician, Harriot devised the < and > symbols.
