2865 Laurel

Orbit and classification

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. No precoveries were taken and the asteroid's observation arc begins with its discovery observation in 1935.

Physical characteristics

Laurel has been characterized as a common S-type asteroid by PanSTARRS photometric survey.

Rotation period

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 hours with a brightness variation of 0.15 in magnitude ().

Diameter and albedo

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. The Collaborative Asteroid Lightcurve Link agrees with IRAS and derives an albedo of 0.24 and a diameter 14.8 kilometers.

Naming

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. The official naming citation was published by the Minor Planet Center on 1 September 1993 (M.P.C. 22496), based on a suggestion by Gareth V. Williams and others.
