2340 Hathor is an asteroid that was discovered on October 22, 1976 by C.T. Kowal at Palomar. Like the other objects of Aten type, Hathor is named for an Egyptian deity. Known as a sky-goddess and the daughter of Ra, Hathor was also identified with Aphrodite. The name was proposed by E. Helin, who made an independent discovery of the object, and also made crucial recovery observations in 1981. Hathor was the 3rd Aten asteroid to be numbered.
