(9577) Gropius is an asteroid of the inner main belt , which was discovered by the German astronomer Freimut Börngen on February 2, 1989 at the Tautenburg Observatory ( IAU code 033) in the Thuringian Tautenburg Forest .
The asteroid belongs to the Nysa group, a group of asteroids named after (44) Nysa (also called the Hertha family, after (135) Hertha ). The timeless (non- osculating ) orbital elements of (9577) Gropius are almost identical to those of the four smaller asteroids, assuming the absolute brightness of 15.7, 15.1, 17.1 and 17.4 compared to 15.0 (14217) Oaxaca , (70183) 1999 RA 3 , (227214) 2005 QU 177 and (312754) 2010 TG 98 .
The track from (9577) Gropius was secured in 1998 so that numbering could be assigned. On February 2, 1999, ten years to the day after its discovery, the asteroid was named after the German architect Walter Gropius , the founder of the Bauhaus , at the suggestion of Freimut Börngen . In 1998 Börngen named an asteroid in the outer main belt after the Bauhaus: (8502) Bauhaus .
