72 Feronia(minor planet designation:72 Feronia) is a quite large and darkmain beltasteroid.It was the first asteroid discovery byC. H. F. Peters,on May 29, 1861,[7]fromHamilton College,New York State.It was initially thought that Peters had merely seen the already known asteroid66 Maja,butT.H. Saffordshowed that it was a new body. Safford named it afterFeronia,aRomanfertilitygoddess.[8]
This asteroid is orbiting theSunwith aperiodof 3.41 years, having asemimajor axisof2.266AUand aneccentricityof 0.121. Theorbital planeis inclined by an angle of 5.4° to theplane of the ecliptic.This is a spectral type TDG asteroid with a cross-section size of 84 km. The asteroid has an estimated rotation period of 8.09 h. Hanuš et al. (2013) gives two possible solutions for the pole in ecliptic coordinates: (λ1,β1) = (287°, −39°) or (λ1,β1) = (102°, −55°).
