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.

8229 Kozelský           Discovered 1996 Dec. 28 by M. Wolf and L. Sarounova at Ondrejov.
Named in honor of František Kozelský (b. 1913), a Czech telescope maker well-known for his work in collaboration with V. Gajdušek. Kozelský made a set of unique fine-mechanics tools that allowed Gajdušek to produce a number of telescope mirrors, resulting finally in the production of six excellent 0.6-m mirrors, two of them now used at the Ondřejov and the Kleť observatories in telescopes devoted to observations of minor planets. Kozelský also made a series of eight 0.2-m refracting telescopes, twenty 0.3-m reflecting telescopes, and several coelostats for small observatories in Czech Republic and Slovakia. Name proposed by the discoverers, following a suggestion by C. Polášek.
