72 Feronia (/fəˈroʊniə/ fə-ROH-nee-ə) is a quite large and dark main belt asteroid. It was the first asteroid discovery by C. H. F. Peters, on May 29, 1861 from Hamilton College, New York State. It was initially thought that Peters had merely seen the already known asteroid 66 Maja, but T.H. Safford showed that it was a new body. Safford named it after Feronia, a Roman fertility goddess.[4]
