72 Feronia is a quite large and dark main belt asteroid. It was the first asteroid discovery by C. H. F. Peters, on May 29, 1861,^[7] 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.^[8]

This asteroid is orbiting the Sun with a period of 3.41 years, having a semimajor axis of 2.266 AU and an eccentricity of 0.121. The orbital plane is inclined by an angle of 5.4° to the plane 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°).
