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.

| 7331 Balindblad | Discovered 1985 Oct. 15 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory. |
| Named in honor of Bertil A. Lindblad (b. 1921) of the Lund Observatory, in recognition of his lifetime work on meteor orbits; his long-term effort in establishing a database for all meteor orbits, now generally used by all meteor workers; his stewardship of IAU Commission 22, which he served as president in the early 1970s; and, in particular, his contribution to starting the very successful "Asteroids, Comets, Meteors" series of conferences. Name suggested and citation written by I. P. Williams. |
