268 Adorea is a very large Main belt asteroid. It is classified as a primitive carbonaceous F-type/C-type asteroid.
Adorea is one of the Themis family members, meaning that it is a fragment of the original body that shattered in an ancient cataclysm that resulted in the formation of the family.
It was discovered by A. Borrelly on June 8, 1887 in Marseilles.
