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 and is probably composed of primitive carbonaceous material. The spectrum of the asteroid displays evidence of aqueous alteration. It is the namesake of the Chloris family of asteroids.
