Named in honor of Galina Richardovna Kastel’, well-known expert on the study of the motions of minor planets and comets, and a staff member of the Institute for Theoretical Astronomy since 1962. She contributed much to the study of the 1886 close approach of periodic comet Brooks 2 to Jupiter. For more than a quarter of a century she has headed the ITA service on comets and fast-moving minor planets, maintaining contacts with the IAU Central Bureau for Astronomical Telegrams and supplying observers in the U.S.S.R. with the necessary information on orbits and ephemerides. She also put much effort into the identification and orbit determination of minor planets observed in the course of the program at the Crimean Astrophysical Observatory, and the success of this program is in no small measure due to her help.
