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.

6481 Tenzing           Discovered 1988 Sept. 9 by A. Mrkos at Klet.
Tenzing Norgay (1914-1986) was a Nepalese mountain climber of the Sherpa tribe. On 1953 May 29, as members of a British party, Tenzing Norgay and the New Zealand mountaineer Edmund Hillary became the first to scale the summit of Mount Everest---and return. The name was suggested by M. Tichy.
