(13478) Fraunhofer is an asteroid of the inner main belt , which was discovered on February 27, 1976 by the German astronomer Freimut Börngen at the Thuringian State Observatory Tautenburg ( IAU code 033) in the Tautenburg Forest in Thuringia .

The asteroid belongs to the Hungaria group . The 9: 2 orbital resonance with the planet Jupiter is characteristic of this group . The namesake for the Hungaria group is the asteroid (434) Hungaria . The solar orbit of (13478) Fraunhofer is steeply inclined at more than 18 ° in relation to the ecliptic of the solar system , another characteristic of Hungaria asteroids.

(13478) Fraunhofer was named on July 26, 2000 after the German optician and physicist Joseph von Fraunhofer (1787–1826) who founded scientific telescope construction as an autodidact at the beginning of the 19th century .
