(6931) Kenzaburo is an asteroid of the main belt , which on 4 November 1994 by Japanese amateur astronomers Kin EnDate and Kazuro Watanabe at Kitami Observatory ( IAU code 400) on Hokkaido was discovered.
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(6931) Kenzaburo was named on August 8, 1998 after the Japanese writer Kenzaburō Ōe (* 1935), who was awarded the 1994 Nobel Prize for Literature .
