(27758) Michelson is an asteroid of the outer main belt , which was discovered by the German astronomers Freimut Börngen and Lutz D. Schmadel on September 22, 1991 at the Tautenburg Observatory ( IAU code 033) in the Thuringian Tautenburg Forest .
The Italian astronomer Vincenzo Zappalà defines in a publication from 1995 (et al.) That 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 , as well as 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. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (27758) Michelson assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid .
The track from (27758) Michselson was secured in 2001, so that a numbering could be assigned. The asteroid was named on November 1 of the same year at the suggestion of Freimut Börngen after the physicist Albert Abraham Michelson (1852-1931). Michelson received the Nobel Prize for Physics in 1907 for his optical precision instruments ( Michelson interferometer ) and the spectroscopic and metrological investigations carried out with them. As early as 1970, a lunar crater on the northern side of the moon was named after Michelson: Lunar crater Michelson .
