410 Chloris is a very large main-belt asteroid that was discovered by Auguste Charlois on January 7, 1896, in Nice. It is classified as a C-type asteroid[5] and is probably composed of primitive carbonaceous material. The spectrum of the asteroid displays evidence of aqueous alteration.[6] It is the namesake of the Chloris family of asteroids.
Photometrics of this asteroid made in 1979 gave a light curve with a period of 32.50 hours with a brightness variation of 0.28 in magnitude.[5]
