(10804) Amenouzume is an asteroid of the main middle belt , an asteroid field between Mars and Jupiter . The asteroid was discovered on November 23, 1992 by the Japanese astronomer Takeshi Urata at the Nihondaira Observatory ( IAU code 385). The Nihondaira Observatory is located in the Chūbu region on Honshū Island . The asteroid had already been sighted on October 2, 1978 under the provisional designation 1978 TV 7 at the Crimean Observatory in Nautschnyj .
The mean diameter of the asteroid was calculated to be 9.428 km (± 0.025) and the albedo to be 0.129 (± 0.005).
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel resulted in a division of all investigated asteroids into C, S and V types (10804) assigned to the C asteroids .
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Dora family, a group of asteroids named after (668) Dora .
(10804) Amenouzume was named after Amenouzume on November 23, 1992 . Amenouzume is a female kami in Shinto mythology . The asteroids (10385) Amaterasu and (10619) Ninigi were also named after gods in this mythology on March 20, 2000 .
