It was discovered on 22 February 1939, by French astronomer André Patry at Nice Observatory in southeastern France, and later named after astronomer Auguste Charlois. Orbit and classification Charlois is a carbonaceous C-type asteroid and a member of the Eunomia family, a large group of otherwise mostly S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central main-belt at a distance of 2.3–3.1 AU once every 4 years and 4 months (1,595 days). Its orbit has an eccentricity of 0.15 and an inclination of 12° with respect to the ecliptic. As no precoveries were taken and no prior identifications were made, the body's observation arc begins with its discovery observation in 1939. Physical characteristics Diameter and albedo According to the 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, Charlois measures between 20.3 and 27.6 kilometers in diameter, and its surface has an albedo between 0.077 and 0.12, while the Collaborative Asteroid Lightcurve Link derives an albedo of 0.079 and a diameter of 23.7 kilometers based on an absolute magnitude of 11.5. Rotation period In November 2007, a rotational lightcurve, constructed from photometric observations by Crag Bennefeld at the Rick Observatory, gave a rotation period of 6.653 0.008 hours with a brightness variation of 0.23 in magnitude (U=2). Another lightcurve, obtained by French astronomers Pierre Antonini and René Roy in February 2013, gave a period of 5.866 0.0003 hours with an amplitude of 0.18 (U=2). Naming This minor planet was named in memory of French astronomer Auguste Charlois (1864–1910), an early discoverer of minor planets at the Nice Observatory where this asteroid was discovered. He was a pioneer during the transition from visual to photographic discoveries in the late 19th century. Until his homicide in 1910, he had discovered 99 asteroids. The official 1510 naming citation was published by the Minor Planet Center on 30 June 1977 (M.P.C. 4190). References 30em 2017-03-29 last obs.
