It was discovered by Alphonse Borrelly on 6 March 1885 in Marseille and was named after Asporina, a goddess worshipped on Mount Asporenus (or Aspordenus), Asia Minor.[2] This location is known in the modern day as the Yunt Mountains,[3] and Asporina is sometimes identified with the goddess Cybele.
The spectrum of 246 Asporina reveals the strong presence of the mineral olivine, a relative rarity in the asteroid belt.[4]
