2754 Efimov, provisionally named 1966 PD, is a main-belt binary asteroid discovered on August 13, 1966 by Tamara Smirnova at Nauchnyj.[1] It is named in memory of the aviator Mikhail Nikiforovich Efimov (1881–1919), who was the first to realize steep turns and dives.[2]
Astronomers discovered a moon around the asteroid in 2006 using lightcurve observations, with a diameter of 1.29 kilometers and an orbital period of 14 hours and 46 minutes.[3]
