(8502) Bauhaus is an asteroid of the outer main belt that was discovered by the German astronomers Freimut Börngen and Lutz D. Schmadel on October 14, 1990 at the Tautenburg Observatory ( IAU code 033) in the Thuringian Tautenburg Forest . Unconfirmed sightings of the asteroid had already occurred in December 1985 (under the provisional designation 1985 YP 1 ) at the Observatoire de Calern in the French canton of Le Bar-sur-Loup .
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. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (8502) Bauhaus assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid .
The timeless (non- osculating ) orbital elements of (8502) Bauhaus are almost identical to those of the smaller one, assuming the absolute brightness of 15.2 compared to 12.6, asteroids (147394) 2003 EB 62 .
The track from (8502) Bauhaus was secured in 1998 so that numbering could be assigned. The asteroid was named on August 8 of the same year at the suggestion of Freimut Börngen after the Bauhaus design school , which was founded in 1919 by Walter Gropius . The asteroid of the inner main belt (9577) discovered by Börngen in 1999 was named after Walter Gropius .
