361 Bononia /bəˈnoʊniə/ is a very large, resonant Hilda asteroid located in the outermost region of the asteroid belt.[2] It is classified as a D-type asteroid and is probably composed of organic rich silicates, carbon and anhydrous silicates. It was discovered by Auguste Charlois on 11 March 1893, in Nice, and assigned the prov. designations A893 EF and 1893 P.
