Leo Minor is a relatively new constellation, and has no myths associated with it. It was first depicted in 1687 in Johannes Hevelius’ Catalogus Stellarum Fixarum.
In 1845, the catalogue was revised by Francis Baily, who assigned Greek letters to stars that were brighter than magnitude 4.5, but he did not give the constellation’s brightest star the designation Alpha in his British Association Catalogue.
In 1870, the English astronomer Richard A. Proctor renamed the constellation to Leaena, or the Lioness, in an attempt to shorten constellation names in order to make them easier to manage on star charts, but the name was not widely adopted.
