2985 Shakespeare (prov. designation: Шаблон:Mp) is a stony Koronian asteroid from the outer region of the asteroid belt. It was discovered on 12 October 1983, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, and later named after William Shakespeare.[1][2] The presumed S-type asteroid has a rotation period of 6.1 hours and measures approximately Шаблон:Convert in diameter.
Classification and orbit
The S-type asteroid is a member of the Koronis family, a group consisting of about 200 known bodies. It orbits the Sun in the outer main-belt at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,756 days). Its orbit has an eccentricity of 0.05 and an inclination of 3° with respect to the ecliptic.[3] It was first identified as Шаблон:Mp at Goethe Link Observatory in 1962. The body's observation arc begins with its identification Шаблон:Mp at Crimea–Nauchnij, 7 years prior to its official discovery observation at Anderson Mesa.[2]
Naming
This minor planet was named after William Shakespeare (1564–1616), the English renaissance dramatist and poet.[1] The approved naming citation was published by the Minor Planet Center on 29 September 1985 (Шаблон:Small).[4]
Physical characteristics
Rotation period and poles
Three different rotational lightcurves, obtained from photometric observations taken at the Palomar Transient Factory and a group of seven observatories, respectively, found a concurring rotation period of 6.06–6.08 hours with a brightness variation between 0.37 and 0.53 magnitude (Шаблон:Small).[5][6][7]
Diameter and albedo
According to the space-based NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the body has an albedo of 0.26 and measures 10.5 kilometers in diameter,[8][9] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Koronis family of 0.24 and calculates a diameter of 10.3 kilometers with an absolute magnitude of 12.1.[10]
