1954 Kukarkin, provisional designation 1952 PH, is an eccentric, carbonaceous asteroid and slow rotator from the outer regions of the asteroid belt. It was discovered by Russian female astronomer Pelageya Shajn at the Crimean Simeiz Observatory on 15 August 1952.[6]
The eccentric asteroid orbits the Sun at a distance of 2.0–3.9 AU once every 5.05 years (1,844 days). Its orbit has a notably high eccentricity of 0.31 and an inclination of 15° with respect to the ecliptic.[1]
The body is a slow rotator, with a long period of 136.40±0.03 hours, measured at Los Algarrobos Observatory, Uruguay (I38) during a favorable opposition in 2012. The well-defined rotational light-curve had brightness variation of 0.8±0.05 in magnitude (U=3-).[5]
While observations taken by NEOWISE gave an albedo of 0.2608±0.0155 and a diameter of 13.659±0.309 kilometers,[4] the Asteroid Lightcurve Database assumes the body to be a C-type asteroid with a significantly lower albedo of 0.057, and hence a much larger diameter of about 31 kilometers.[3]
The asteroid 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]
