(13559) Werth is an asteroid of the main outer belt . It was discovered by the German astronomers Lutz D. Schmadel and Freimut Börngen on September 4, 1992 with the Schmidt telescope of the Karl Schwarzschild Observatory ( IAU code 033) in the Tautenburg Forest . The asteroid had already been sighted: on September 17, 1976 under the provisional designation 1976 SK 10 at the Felix Aguilar Observatory in Argentina and on October 21, 1982 (1982 US 8 ) at the Crimean Observatory in Nautschnyj .
The mean diameter of the asteroid was calculated to be 11.312 (± 0.126).
The railway from (13559) Werth was secured in 2000 so that numbering could be assigned. The asteroid was named on June 24, 2002 at the suggestion of Lutz D. Schmadel after the German television journalist and author Hildegard Werth , who is known as a science reporter for ZDF .
