    12696 Camus, provisional designation 1989 SF1, is a carbonaceous asteroid from the middle region of the asteroid belt, about 9 kilometers in diameter. It was discovered by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile on 26 September 1989.[7]

    The dark C-type asteroid orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,550 days). Its orbit shows an eccentricity of 0.14 and an inclination of 8 degrees from the plane of the ecliptic.[1] In 2006, a photometric light-curve analysis by Julian Oey at the Leura Observatory (E17) in Australia rendered rotation period of 3.78±0.04 hours with a brightness amplitude of 0.40 in magnitude (U=3-).[6]

    According to NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an albedo of 0.07 and 0.13 with a corresponding diameter of 9.3 and 7.7 kilometers, respectively.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) assumes a lower albedo of 0.057 and consequently calculates a larger diameter of 11.1 kilometer, as the lower the albedo (reflectivity), the larger the asteroid for a given absolute magnitude (brightness).[3]

    The minor planet was named after French philosopher, author, and journalist, Albert Camus (1913–1960), who won the Nobel Prize in Literature in 1957. He is best known for his novels L'Etranger (The Stranger) and La Peste (The Plague). He defended truth, moderation and justice, adhering to liberal humanism and rejecting the dogmatic aspects of both Christianity and Marxism.[2]
