2985 Shakespeare (prov. designation : 1983 TV1 ) 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 .[ 2] [ 9] The presumed S-type asteroid has a rotation period of 6.1 hours and measures approximately 10 kilometers (6.2 miles) 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 .[ 1] It was first identified as 1962 JJ at Goethe Link Observatory in 1962. The body's observation arc begins with its identification 1976 GV at Crimea–Nauchnij , 7 years prior to its official discovery observation at Anderson Mesa.[ 9]
Naming
This minor planet was named after William Shakespeare (1564–1616), the English renaissance dramatist and poet.[ 2] The approved naming citation was published by the Minor Planet Center on 29 September 1985 (M.P.C. 10044 ).[ 10]
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 (U=2/3/2 ).[ 6] [ 7] [ 8]
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,[ 4] [ 5] 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.[ 3]
