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. Safford showed that it was a new body. Safford named it afterFeronia, aRomanfertility goddess.[8]
This asteroid is orbiting theSun with aperiod of 3.41 years, having asemimajor axis of2.266 AU and aneccentricity of 0.121. Theorbital plane is 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°).
