It was discovered on 26 September 1989, by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile, and named after French Nobel Prize laureate in literature Albert Camus.[2][9]
Classification and orbit
Camus is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 2.2â3.0 AU once every 4 years and 3 months (1,551 days). Its orbit has an eccentricity of 0.14 and an inclination of 8° with respect to the ecliptic.[1] The asteroid's observation arc begins with its discovery, as no precoveries were taken and no identifications were made before 1989.[9]
Naming
This minor planet was named after French philosopher, author, and journalist, Albert Camus (1913â1960), who received the Nobel Prize in Literature in 1957.[2]
Camus is best known for his novels L'Etranger (The Stranger) and La Peste (The Plague). His main interests were justice, ethics, and politics. As a liberal humanist, he was against the doctrines of Christianity as well as Marxism.[2] The approved naming citation was published by the Minor Planet Center on 20 March 2000 (M.P.C. 39658).[10]
Physical characteristics
Camus has been characterized as a carbonaceous C-type asteroid by Pan-STARRS photometric survey.[8]
Lightcurves
In October 2006, a rotational lightcurve of Camus was obtained from photometric observations by Julian Oey at the Leura Observatory (E17) in Australia. The lightcurve rendered a rotation period of 3.78±0.04 hours with a brightness amplitude of 0.40 in magnitude (U=3-).[7]
Diameter and albedo
According to NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Camus has an albedo of 0.07 and 0.13 with a corresponding diameter of 9.3 and 7.7 kilometers, respectively.[4][5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a larger diameter of 11.1 kilometer with an absolute magnitude of 13.5.[3]
