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.

6600 Qwerty           Discovered 1988 Aug. 17 by A. Mrkos at Klet.
Qwerty is a popular name for the standard Roman-alphabet typewriter keyboard, based on the first six of the top row of letters. The Qwerty design was patented by Christopher Latham Sholes of Milwaukee, and the first typewriter was produced in 1874. The name was suggested by G. Schilling.
