(8316) Wolkenstein is an asteroid of the main belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory ( IAU code 675) .

The asteroid belongs to the Eos family , a group of asteroids which typically have large semiaxes 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.

(8316) Wolkenstein was on 5 October 1998 by the late medieval singer, poet and composer Oswald von Wolkenstein named (around 1377-1445), of a politician of more than just regional importance and diplomat in the service of the German Emperor Sigismund I was.
