(120481) Johannwalter is an asteroid of the inner main belt , which was discovered by the German astronomers Freimut Börngen and Lutz D. Schmadel on September 24, 1992 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 (120481) Johannwalter are almost identical to those of 17 other asteroids, of which (11344) 1996 XH 31 with 14.7 is the largest, assuming absolute brightness .
The track from (120481) Johannwalter was secured in 2006 so that a numbering could be assigned. The asteroid was named on August 9 of the same year at the suggestion of Freimut Börngen after the cantor and editor of the first Protestant choral hymn book Johann Walter (1496–1570). Börngen has named a number of asteroids after Protestant themes, for example (118173) Barmen based on the Barmen Theological Declaration of 1934 and (118178) Rinckart after Martin Rinckart . The lunar crater Walter, on the other hand, a crater on the northern front of the moon , was named in 1979 after the German first name Walter .
