Juno, the third asteroid identified in the main-belt, was discovered by Karl Ludwig Harding in 1804. This observation occurred during his tenure at the observatory in Lilienthal, solidifying his role within the celestial police, a collective of twenty-four astronomers tasked with searching for additional planets within the Solar System.
Academic Foundation and Early Career
Born in Lauenburg in 1765, Harding attended the University of Göttingen from 1786 until 1789. His curriculum included physics, mathematics, and theology. In 1796, he accepted a position as a tutor for the son of Johann Hieronymus Schröter. This role provided him access to an advanced observatory in Lilienthal, where he transitioned into an inspector and observer.

Harding left his position in Lilienthal in 1805, where he was succeeded by Friedrich Wilhelm Bessel. He relocated to the University of Göttingen to serve as an extraordinary professor of astronomy. By 1812, he achieved the rank of ordinary professor. His research at the Göttingen Observatory continued until his death in 1834, including a long-term collaboration with Carl Friedrich Gauss starting in 1807.
Contributions to Mapping and Discovery
Beyond his asteroid detection, Harding identified three comets and multiple variable stars, including R Virginis, R Aquarii, R Serpentis, and S Serpentis. He also cataloged new nebulae, notably the Helix Nebula. His primary publication, the Atlas novus coelestis, released between 1808 and 1823, cataloged 120,000 stars and notably removed mythological figures from star mapping, prioritizing scientific precision over artistic tradition.
Institutional Recognition
Harding held memberships in several prominent scientific organizations, including the Royal Prussian Academy of Sciences and the Royal Society. He was named a corresponding member of the Royal Academy of Sciences in Göttingen in 1803 and a full member in 1806. Additionally, he earned the Lalande Prize in 1804 and was awarded the title of Hofrath by the government.
