1510 Charlois, provisional designation 1939 DC, is a carbonaceous Eunomia asteroid from the middle region of the asteroid belt, approximately 24 kilometers in diameter.

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.[2][12]

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.[1] As no

precoveries were taken and no prior identifications were made, the body's observation arc begins with its discovery observation in 1939.[12]

Physical characteristics

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.077 and 0.12,[4][5][6][7][8] 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.[3]
