(6913) Yukawa is a main inner belt asteroid discovered on October 31, 1991 by Japanese amateur astronomers Kin Endate and Kazurō Watanabe at the Kitami Observatory ( IAU code 400) on Hokkaidō .
The mean diameter of the asteroid was roughly calculated to be 3.320 (± 0.472) kilometers, the albedo also roughly 0.343 (± 0.120).
(6913) Yukawa was named on August 8, 1998 after the Japanese physicist Hideki Yukawa (1907–1981), who received the Nobel Prize in Physics in 1949 "for his prediction of the existence of mesons based on the theory of nuclear forces " .
