410 Chloris

Chloris (minor planet designation: 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[4] and is probably composed of primitive carbonaceous material. The spectrum of the asteroid displays evidence of aqueous alteration.[5] It is the namesake of the Chloris family of asteroids.
