1954 Kukarkin (prov. designation: Template:Mp) is an asteroid and slow rotator on an eccentric orbit from the outer regions of the asteroid belt. It was discovered on 15 August 1952, by Russian astronomer Pelageya Shajn at Simeiz Observatory on the Crimean peninsula.[1] The asteroid has a exceptionally long rotation period of 136.4 hours and measures approximately Script error: No such module "convert". in diameter. It was named after astronomer Boris Kukarkin.[2]
Orbit and classification
Kukarkin orbits the Sun in the outer main-belt at a distance of 2.0–3.9 AU once every 5.03 years (1,838 days). Its orbit has an eccentricity of 0.31 and an inclination of 15° with respect to the ecliptic.[3] No precoveries were taken prior to its discovery.[1]
Naming
This minor planet is named after stellar astronomer Boris Vasilyevich Kukarkin (1909–1977), a well-known specialist for variable stars, the structure of stellar systems, and professor at Moscow State University. Kukarkin started and edited the General Catalogue of Variable Stars that was first published in 1948. He also served as vice-president of the Astronomical Council of Academy of Sciences of the USSR as well as of the International Astronomical Union and was the president of its Commission 27.[2] The approved naming citation was published by the Minor Planet Center on 1 June 1980 (M.P.C. 5358Script error: No such module "Check for unknown parameters".).[4]
Physical characteristics
Kukarkin is a slow rotator, with a long period of Script error: No such module "val". hours, measured at Los Algarrobos Observatory, Uruguay (I38) during a favorable opposition in 2012. The well-defined rotational lightcurve had brightness variation of Script error: No such module "val". magnitude (U=3-Script error: No such module "Check for unknown parameters".).[5]
While observations taken by NEOWISE gave an albedo of Script error: No such module "val". and a diameter of Script error: No such module "val". kilometers,[6] the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous C-type asteroid of 0.057 and calculates a significantly larger diameter of 30.6 kilometers, as the lower the albedo, the larger the body's diameter at a constant absolute magnitude.[7]
