7385 Aktsynovia, provisional designation 1981 UQ11, is a stony asteroid from the inner regions of the asteroid belt, about 4 kilometers in diameter. It was discovered on 22 October 1981, by Soviet–Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula.[5]
The S-type asteroid orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 8 months (1,349 days). Its orbit shows an eccentricity of 0.13 and is tilted by 4 degrees to the plane of the ecliptic. It has a rotation period of 4.1 hours[4] and an albedo of 0.20, as assumed by the Collaborative Asteroid Lightcurve Link (CALL).[3]
The minor planet was named in memory of Lyudmila Mikhailovna Aktsynova (1910–1997) and her husband Arkadij Vsevolodovich Aktsynov (1910–1997). Both were masters of portraiture and landscape painting. They depicted the beauties of nature in various parts of Russia, including Siberia, Baikal, Sayany, Altaj and Volga.[2][5]
