5101 Akhmerov, provisional designation 1985 UB5, is a stony asteroid from the outer region of the asteroid belt, about 12 kilometers in diameter. It was discovered on 22 October 1985, by Russian female astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[5]
The S-type asteroid is a member of the Eos family, an orbital group of more than 4,000 asteroids, which are well known for mostly being of stony composition with a relatively high albedo. It orbits the Sun at a distance of 2.7–3.4 AU once every 5 years and 3 months (1,903 days). Its orbit shows an eccentricity of 0.12 and is tilted by 11 degrees to the plane of the ecliptic. In 2011, photometric light-curve observations at the U.S. Palomar Transient Factory rendered a rotation period of 4.3 hours.[4] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.14, identical to the albedo of the asteroid family's namesake, 221 Eos.[3]
The minor planet was named in honor of Vadim Zinov’evich Akhmerov (b. 1929), doctor in the Crimean Peninsula, who has returned health to many people during his 45-year medical service. He has worked in the maternity hospital in Alushta, Crimea, since 1980.[2]
