Karl Ludwig Harding (born Sept. 29, 1765, Lauenburg [Germany]—died Aug. 31, 1834, Göttingen) was an astronomer who discovered (1804) and named Juno, the third minor planet to be detected. He studied at the University of Göttingen under Georg Lichtenberg and later served as assistant to J.H. Schröter at Schröter’s Lilienthal Observatory. In 1805, Harding returned as a professor to Göttingen, where he remained until his death. He is credited with the discovery of three comets, in 1813, 1824, and 1832. His most important published work was the Atlas novus coelestis (1808–23), which catalogued more than 120,000 stars.
