Leo Minor is a small, faint constellation in the northern sky, with only one star brighter than fourth magnitude. The constellation’s name means “the smaller lion” in Latin.
Leo Minor was created by the Polish astronomer Johannes Hevelius in 1687. Hevelius created the constellation from 18 stars between the larger constellations Leo and Ursa Major.
The constellation is located between Ursa Major to the north, Cancer to the southwest, Lynx to the west, and Leo, which represents the larger lion, to the south.
Notable deep sky objects in Leo Minor include Hanny’s Voorwerp and the interacting galaxies Arp 107.
