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.

15045 Walesdymond           Discovered 1998 Dec. 10 by Spacewatch at Kitt Peak.
William Wales and Joseph Dymond were two young Yorkshire men sent to the shores of Hudson Bay by the Royal Society of London to observe the transit of Venus on 1769 June 3. They stayed for over a year at Fort Prince of Wales, near modern-day Churchill, Manitoba.
