Petit Lion
Johannes Hevelius first depicted Leo Minor in 1687 when he outlined ten new constellations in his star atlas "Firmamentum Sobiescianum", and included 18 of its objects in the accompanying "Catalogus Stellarum Fixarum". Hevelius decided upon Leo Minor or Leo Junior as a depiction that would align with its beastly neighbours the Lion and the Great Bear. In 1845, English astronomer Francis Baily revised the catalogue of Hevelius's new constellations, and assigned a Greek letter known as Bayer designation to stars brighter than apparent magnitude 4.5. Richard A. Proctor gave the constellation the name "Leaena" "the Lioness" in 1870, explaining that he sought to shorten the constellation names to make them more manageable on celestial charts.
