7164 Babadzhanov           Discovered 1984 Mar. 6 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Pulat Babadzhanov (b. 1930), director of the Institute of Astrophysics, Tajik Academy of Sciences, Dushanbe. Babadzhanov's research includes the photographic investigation of meteors, the physics and dynamics of meteors, the evolution of meteoroid streams and the association of comets and minor planets with meteor showers. He has served as rector of the Tajik State University, vice president of the Tajik Academy of Sciences and as president of IAU Commission 22.
