Stella Ludoviciana is a modern star name for HD 116798 (Vmag=7.58) adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is modern Latin. It is the name of a faint star between Alcor and Mizar in constellation Ursa Major.
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]
Mythology
