72 Feronia
main-belt asteroid
72 Feronia (minor planet designation: 72 Feronia) is a somewhat large and dark Main belt asteroid. It was the first asteroid that C. H. F. Peters discovered on May 29, 1861, in Hamilton College, New York.[6] At first, people thought that Peters saw 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.[7]
