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.

7734 Kaltenegger           Discovered 1979 June 25 by E. F. Helin and S. J. Bus at Siding Spring.
Austrian-born Lisa Kaltenegger (b. 1977), at the Harvard-Smithsonian Center for Astrophysics since 2005, is involved in the use of space-based instruments to collect sufficient photons from extrasolar planets to characterize their physical and chemical composition and examine their potential habitability.
