2865 Laurel, provisional designation 1935 OK, is a stony Marian asteroid from the middle region of the asteroid belt, approximately 15 kilometers in diameter. It was discovered by English-born South African astronomer Cyril Jackson at Johannesburg Observatory on 31 July 1935. [9] The asteroid was named after movie comedian Stan Laurel. [2]
Laurel orbits the Sun in the central main-belt at a distance of 2.4–2.7 AU once every 4 years and 1 month (1,497 days). Its orbit has an eccentricity of 0.07 and an inclination of 14 ° with respect to the ecliptic. [1] No precoveries were taken and the asteroid's observation arc begins with its discovery observation in 1935. [9]
Laurel has been characterized as a common S-type asteroid by PanSTARRS' photometric survey. [8]
A rotational lightcurve for this asteroid was obtained from photometric observations by French amateur astronomer Pierre Antonini in September 2005. It gave a longer than average rotation period of 21.5±0.3 hours with a brightness variation of 0.15 in magnitude ( U=2). [7]
According to the space-based surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 14.7 and 25.0 kilometers in diameter and its surface has an albedo between 0.09 and 0.22. [4] [5] [6] The Collaborative Asteroid Lightcurve Link agrees with IRAS and derives an albedo of 0.24 and a diameter 14.8 kilometers. [3]
This minor planet was named after English-born slapstick film comedian Stan Laurel (1890–1965). Together with Oliver Hardy (1892–1957), who was honored with the main-belt asteroid 2866 Hardy, they formed the first great comedy duo in Classical Hollywood cinema. [2] The official naming citation was published by the Minor Planet Center on 1 September 1993 ( M.P.C. 22496), [10] based on a suggestion by Gareth V. Williams and others. [2]
