5101 Akhmerov, provisional designation1985 UB5, is an Eosasteroid from the outer region of theasteroid belt, about 12 kilometers in diameter. It was discovered on 22 October 1985, by Russian astronomerLyudmila Zhuravleva at theCrimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[8] It was later named for Ukrainian surgeonVadim Akhmerov.[2]
Akhmerov is a member of theEos family (606), the largestasteroid family in theouter main belt consisting of nearly 10,000 asteroids.
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 has aneccentricity of 0.12 and aninclination of 11° with respect to theecliptic.[1] A firstprecovery was obtained at the discovering observatory in 1969, extending the body'sobservation arc by 16 years prior to its official discovery observation.[8]
PanSTARRS photometric survey has characterizedAkhmerov as a CX-type asteroid, a transitional group between the carbonaceousC-type asteroid and the metallicX-type asteroids.[3][7]
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer,Akhmerov measures 11.0 kilometers in diameter and its surface has an albedo of 0.19.[4][5] TheCollaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.14 – derived from221 Eos, the largest member and namesake of this orbital family – and calculates a diameter of 12.3 kilometers with anabsolute magnitude of 12.3.[3]
A rotationallightcurve ofAkhmerov was obtained from photometric observations taken at the U.S.Palomar Transient Factory in September 2011. The lightcurve gave arotation period of4.2705±0.0010 hours with a brightness amplitude of 0.33 inmagnitude (U=2).[6]
Thisminor planet was named after Vadim Zinov'evich Akhmerov (born 1929), long-time physician at the maternity hospital inAlushta on the Crimean peninsula.[2] The official naming citation was published by theMinor Planet Center on 4 May 1999 (M.P.C. 34620).[9]
