caption_attribution_description: English: A three-dimensional model of 135 Hertha that was computed using light curve inversion techniques.
context_page_description: Hertha is an asteroid from the inner region of the asteroid belt, approximately 77 kilometers in diameter. Discovered on 18 February 1874 by German–American astronomer Christian Peters at the Litchfield Observatory near Clinton, New York, it was named after the Teutonic and Scandinavian goddess of fertility, Hertha, also known as Nerthus. It orbits among the Nysa asteroid family, but its classification as an metallic M-type asteroid does not match the more common F-type asteroid for this family, suggesting that it may be an interloper. Spectroscopic analysis indicates the possible presence of hydrated silicates indicating that Hertha should possibly be reclassified from its present M-type to the proposed W-type.
  Lightcurve data from Hertha indicates a flattened body, and radar observations indicate that Hertha is non-metallic. Five occultations of stars by the asteroid have been observed between 2000 and 2015.
