8306 Shoko, provisional designation 1995 DY1, is a Florian asteroid and a synchronous binary system from the inner regions of the asteroid belt, approximately 3 kilometers (2 miles) in diameter. It was discovered on 24 February 1995, by Japanese astronomer Akimasa Nakamura at the Kuma Kogen Astronomical Observatory in southern Japan, who named it after Japanese singer-songwriter Shoko Sawada.[1] The likely S-type asteroid has a rotation period of 3.35 hours.[3] The discovery of its 1.3-kilometer minor-planet moon was announced in December 2013.[6]
