2697 Albina, provisional designation Шаблон:Mp, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 52 kilometers in diameter. It was discovered on 9 October 1969, by Russian astronomer Bella Burnasheva at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula. The asteroid was later named after Russian astronomer Albina Serova.[1]
Orbit and classification
Albina orbits the Sun in the outer main-belt at a distance of 3.3–3.8 AU once every 6 years and 9 months (2,455 days). Its orbit has an eccentricity of 0.08 and an inclination of 4° with respect to the ecliptic.[2]
The asteroid was first identified as Шаблон:Mp at Lowell Observatory in 1929. It first used observation was taken at Uccle Observatory in 1936, extending the body's observation arc by 33 years prior to its official discovery at Nauchnyj.[1]
Physical characteristics
Albina has been characterized as an X-type asteroid by Pan-STARRSШаблон:' photometric survey.[3] It has also been dark described as a carbonaceous C-type asteroid in the Lightcurve Data Base.[4]
Rotation period
A rotational lightcurve of Albina was obtained from photometric observations made at the U.S. Palomar Transient Factory in October 2010. The lightcurve gave a rotation period of Шаблон:Val hours with a brightness amplitude of 0.16 in magnitude (Шаблон:Small),[5] and supersedes a previous period of Шаблон:Val hours from a fragmentary lightcurve, obtained by French astronomer Laurent Bernasconi in March 2006 (Шаблон:Small).[6]
Diameter and albedo
According to the space-based surveys carried out by the Infrared Astronomical Satellite (IRAS) and the Japanese Akari satellite, Albina has an albedo of 0.055 and 0.053, with a corresponding diameter of 51.5 and 52.7 kilometers, respectively.[7][8] The Collaborative Asteroid Lightcurve Link derives a lower albedo of 0.039 and a diameter of 51.4 kilometers.[4]
Naming
This minor planet was named after Russian astronomer from Moscow, Albina Serova, who is a friend of the discoverer.[9] The official naming citation was published by the Minor Planet Center on 18 September 1986 (Шаблон:Small).[10]
