Triangulum Australe

Triangulum Australe, also known as the Southern Triangle, is a small and faint constellation situated in the southern celestial hemisphere. Its visibility is optimal from southern latitudes, making it less observable from most northern locations.

Stars

Notable celestial bodies within the constellation include Atria, Beta Trianguli Australis, and Gamma Trianguli Australis.

Clusters

Additionally, the region is home to some interesting deep-sky objects, such as the globular cluster NGC 6025 and the open cluster NGC 5970.

History

Vespucci created a lost catalogue of southern stars, describing a triangle, possibly Triangulum Australe, in his work "Mundus Novus." The constellation's first depiction in 1589 by Petrus Plancius was inaccurate, but Johann Bayer's 1603 atlas, "Uranometria," provided a more precise representation and its current name.
