10916 Okina-Ouna           Discovered 1997 Dec. 31 by N. Sato at Chichibu.
Okina and Ouna are the two small lunar explorers developed by the Japan Aerospace Exploration Agency. They were separated from the main orbiter of the lunar explorer "KAGUYA (SELENE)" in Oct. 2007. Okina and Ouna are also the foster parents of Kaguya in the old Japanese story Kaguya-hime.
