Life and career

Harding was born in Lauenburg. From 1786–89, he was educated at the University of Göttingen, where he studied theology, mathematics, and physics. In 1796 Johann Hieronymus Schröter hired Harding as a tutor for his son. Schröter was an enthusiastic astronomer and owner of a well-equipped observatory in Lilienthal near Bremen, where Harding was soon appointed observer and inspector.In 1800, he was among the 24 astronomers invited to participate in the celestial police, a group dedicated to finding additional planets in the solar system. As part of the group, in 1804, Harding discovered Juno at Schröter's observatory. In the next year he left Lilienthal, where his successor became Friedrich Wilhelm Bessel, as he was appointed extraordinary professor of astronomy at the University of Göttingen, since 1812 as ordinary professor. He worked at Göttingen Observatory, since 1807 as colleague of Carl Friedrich Gauss, until his sudden death in 1834. In addition to Juno, he discovered three comets and the variable stars R Virginis, R Aquarii, R Serpentis and S Serpentis. Furthermore, he found some new nebulae,BOOK, Harding, Karl Ludwig, 1824, Bode, J. E., Johann Elert Bode, Astronomisches Jahrbuch für das Jahr 1827 (Volume 52), Berliner Astronomisches Jahrbuch, Ferd.
