58097 Alimov (provisional designation 1976 UQ1) is a background asteroid and relatively slow rotator from the central region of the asteroid belt, approximately 4 kilometers in diameter.

The asteroid was discovered on 26 October 1976, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[7] It was later named after Russian ecologist Alexandr Alimov.[2]

Orbit and classification

Alimov is a non-family from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 1.9–3.2 AU once every 4 years and 1 month (1,502 days). Its orbit has an eccentricity of 0.26 and an inclination of 13° with respect to the ecliptic.[1]

The asteroid's observation arc begins just 4 days prior to its official discovery observation, with a precovery taken at the Japanese Kiso Observatory on 22 October 1976.[7]

Physical characteristics

Lightcurves

In October 2013, a rotational lightcurve of Alimov was obtained from photometric observations made by astronomers at the Palomar Transient Factory in California. It gave a relatively long rotation period of 78.1729 hours with a brightness variation of 0.26 magnitude ({{{1}}}).[6]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Alimov measures 3.9 and 4.0 kilometers in diameter and its surface has an albedo of 0.136 and 0.152, respectively.[4][5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.7 kilometers with an absolute magnitude of 14.54.[3]

Naming

This minor planet was named after Russian ecologist Alexandr Fyodorovich Alimov (born 1933), president of the Hydrobiological Society and founder of the Russian School of Functional Ecology.[2]

Alimov is known for his theoretical and experimental work on aquatic ecosystems and for the study on the prevention of ecological crisis.[2] The official naming citation was published by the Minor Planet Center on 6 March 2004 (M.P.C. 51190).[8] (Alexandr Fyodorovich Alimov should not be confused with Aleksandr Fyodorovich Akimov, who worked at Chernobyl during the nuclear accident).
