History
It was discovered in on the 23rd of January, 1908 by the German astronomer August Kopff in the city Heidelberg. The name appears to have four different meanings in ancient Greek mythology. The first is Asteria the daughter of the Titans Coeus and Phoebe and the sister of Leto. The second is being one of the fifty daughters of Danaus. The third is Apollodorus stating that Asteria was a daughter of Atlas. The fourth and final is Asteria being the name of a town in Greece.[3] The object was lost in 1908.[4]
