Constellation Lacerta (Lizard)

Lacerta
Lacerta: IAU Constellation Map [150]

Properties

Lacerta is a constellation that fills a 201 square degree gap between the large, bright constellations. The constellation is poor in bright stars, expressionless and therefore a little difficult to find. It is located between Cygnus and Andromeda, roughly level with Deneb. The northernmost part lies in the band of the Milky Way and the center culminates around midnight on August 28th. [9, 15]

History

The constellation was only introduced by Johannes Hevelius from Danzig towards the end of the 17th century. The French Augustin Royer proposed the name of the scepter and the hand of Justitia for this area in 1697 in memory of King Louis XIV. The German astronomer Johann Elert Bode named the constellation Gloria in 1787 in honor of Frederick the Great Prussia. These two strongly political proposals were later dropped in favor of a neutral lizard (Lacerta). [7]
