12690 Kochimiraikagaku           Discovered 1988 Nov. 5 by T. Seki at Geisei.
Kochi-Mirai-Kagakukan (Kochi city future science museum) is to be built in the heart of the city and will open in 2017. It will be equipped with a planetarium and is expected to play a role for astronomy education for children.
