It was discovered by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 24 January 1968. The asteroid was named after Russian composer Aleksandra Pakhmutova. Orbit and classification Pakhmutova orbits the Sun in the outer main-belt at a distance of 2.7–3.4 AU once every 5 years and 5 months (1,984 days). Its orbit has an eccentricity of 0.11 and an inclination of 13° with respect to the ecliptic. It was first identified as 1942 JM at Johannesburg Observatory in 1942. Its first used observation was made in 1968, when it was identified as 1966 US at the discovering observatory, extending the body's observation arc by 2 years prior to its official discovery observation. Physical characteristics Pakhmutova has been characterized as a carbonaceous C-type asteroid. Diameter and albedo This asteroid has a mean-diameter between 33.53 and 37.68 kilometers, and an albedo between 0.05 and 0.0752, as measured by the space-based Akari, IRAS and WISE/NEOWISE surveys. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0574 and a diameter of 33.41 kilometers with an absolute magnitude of 11.1. Rotation period and poles In February 2006, a rotational lightcurvelightcurve-plot was obtained by American astronomer Brian Warner at his Palmer Divide Observatory (716) in Colorado. Lightcurve analysis gave a rotation period of 17.490 hours with a brightness variation of 0.50 in magnitude (U=3-). Photometric observations at the Palomar Transient Factory in February 2012, gave a period of 17.5226 hours and an amplitude of 0.49 magnitude (U=2). In 2011, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue (UAPC) and other sources gave a period 17.5157 hours, as well as a spin axis of (22.0°, –76.0°; 167.0°, –40.0°) in ecliptic coordinates (λ, β) (U=2). Naming This minor planet was named in honor of the Russian composer Aleksandra Pakhmutova, one of the best known figures in Soviet and later Russian popular music. The official 1889 naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3936).
