(9307) Regiomontanus is an asteroid of the inner main belt , which was discovered by the German astronomer Freimut Börngen on August 21, 1987 at the Thuringian State Observatory Tautenburg ( IAU code 033).
The asteroid belongs to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. The timeless (non- osculating ) orbital elements of (9307) Regiomontanus are almost identical to those of five smaller asteroids if one considers the absolute magnitudes of 16.1, 15.8, 15.6, 16.1 and 17.3 compared to 14 , 4 starts: (67365) 2000 LA 23 , (67973) 2000 XV 5 , (72022) 2000 XE 22 , (162673) 2008 SF 304 and (310886) 2003 QK 24 .
The track from (9307) Regiomontanus was secured in 1998 so that numbering could be assigned. The asteroid was named on February 2, 1999 at the suggestion of Freimut Börngen after the mathematician and astronomer of the late Middle Ages Regiomontanus . A lunar crater in the southern lunar hemisphere was named after Regiomontanus as early as 1935 : lunar crater Regiomontanus .
