4165 Didkovskij           Discovered 1976 Apr. 1 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Named in honor of Leonid Vladimirovich Didkovskij (b. 1948), astrophysicist and deputy director of the Crimean Astrophysical Observatory. He is known for his research on the brightness oscillations of the sun, for his development of scientific instrumentation for the Soviet space telescope "Astron" and for his work with the active main mirror on the 1.7-m Space Telescope "Spectrum UV", an international project.
