Concordance, Etymology, History
Variants:
The name was made popular with its mention in Allen (1899)[1].
The star was observed on 2 December 1722 by the German theologian and scientist Johann Georg Liebknecht (1679–1749). He thought he observed relative motion (proper motion) to the neighbouring stars, Mizar and Alcor, and, therefore, mistook it for a planet. Subsequently, he named it after Louis V, Landgrave of Hesse-Darmstadt. Unknown to Liebknecht, it had been previously observed by the Italian mathematician and Benedictine monk Benedetto Castelli (1578–1643) in 1616.[3]
