10412 Tsukuyomi           Discovered 1997 Dec. 21 by Y. Shimizu and T. Urata at the Nachi-Katsuura Observatory.
According to myth, Tsukuyomi-no-mikoto, the Japanese god of night and the moon, was born from the right eye of the god Izanaki. It is said that he made his older sister, the goddess Amaterasu, very angry and caused the separate appearance of the sun in the day and the moon at night.
