(256813) Marburg is an asteroid of the main central belt , which is located between Mars and Jupiter .
It was discovered on February 11, 2008 by the German amateur astronomers Rainer Kling and Erwin Schwab from the Hans-Ludwig-Neumann-Observatory ( IAU code B01) on the Kleiner Feldberg im Taunus . According to Erwin Schwab, the asteroid has a diameter between 2 and 3 kilometers.
The asteroid was named on October 12, 2011 after the Hessian university town of Marburg . The Philipps University of Marburg , founded in 1527, is the oldest still existing university of Protestant origin in the world. The reason for the name for the discoverers was that the city with the Gerling observatory ( IAU code 525), which was established in 1841, is one of the oldest observatories in Hesse. From there, the dwarf planet (1) Ceres was measured astrometrically as early as 1849 . Today the observatory is only opened for exhibitions from time to time.
