(10847) Koch is an asteroid of the outer main belt , which was discovered by the German astronomer Freimut Börngen on January 5, 1995 at the Tautenburg Observatory ( IAU code 033) in the Thuringian Tautenburg Forest .
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. Eos asteroids usually have a rather bright surface. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), however, a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (10847) Koch assumed a dark surface, after which, roughly seen, be a C asteroid .
The orbit of the asteroid was secured in 1999 so that numbering could be assigned. (10847) Koch was named after the German physician and microbiologist Robert Koch on January 24, 2000 at the suggestion of Freimut Börngen . Along with Louis Pasteur, Koch was the founder of modern bacteriology and microbiology and received the Nobel Prize in Physiology or Medicine in 1905 "for his investigations and discoveries in the field of tuberculosis ". An asteroid in the middle main belt was named after Pasteur in 1991, (4804) Pasteur , and after Robert Koch in 1970 a lunar crater in the southern lunar hemisphere, Koch lunar crater .
