Named in memory of Vsevolod Vladimirovich Fedynskij (1908-1978), an outstanding expert in reconnaissance geophysics, physics of the earth and meteor astronomy, a capable organizer of scientific research, Vice President of the Committee on Meteorites of the U.S.S.R. Academy of Sciences, President of IAU Commission 22 (1958-1964), and an honorary member and Vice President of the All-Union Astronomy and Geodesy Association.
