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]
