(21075) Heussinger is an asteroid of the main belt that was discovered on September 12, 1991 by the German astronomers Freimut Börngen and Lutz D. Schmadel at the observatory of the Thuringian State Observatory in Tautenburg ( IAU code 033).

Using a multi-stage process, including using hierarchical cluster analysis , Milani et al. based on orbital data from AstDyS, a grouping of main belt asteroids was carried out. This resulted in a cluster of asteroids to which (21075) Heussinger among others (6769) Brokoff belongs and which overlaps with the Hertha family. It is possible that (21075) Heussinger belongs to the Hertha family, although this is only a basis for necessary further investigations.

(21075) Heussinger is named after the Catholic priest and Minorite Father Adalbero Heussinger (1923–2011), who held the post of Apostolic Penitentiary in the Vatican for 37 years .
