5101 Akhmerov, provisional designation 1985 UB5, is an Eos asteroid from the outer region of the asteroid belt, about 12 kilometers in diameter. It was discovered on 22 October 1985, by Russian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[8] It was later named for Ukrainian surgeon Vadim Akhmerov.[2]

Orbit and classification

Akhmerov is a member of the

606), the largest asteroid family in the outer
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 an eccentricity of 0.12 and an inclination of 11° with respect to the ecliptic.[1] A first precovery was obtained at the discovering observatory in 1969, extending the body's observation arc by 16 years prior to its official discovery observation.[8]

Physical characteristics

PanSTARRS photometric survey has characterized Akhmerov as a CX-type asteroid, a transitional group between the carbonaceous C-type asteroid and the metallic X-type asteroids.[3][7]

Diameter and albedo

According to the survey carried out by the

NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Akhmerov measures 11.0 kilometers in diameter and its surface has an albedo of 0.19.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.14 – derived from 221 Eos, the largest member and namesake of this orbital family – and calculates a diameter of 12.3 kilometers with an absolute magnitude of 12.3.[3]
