Triangulum Australe (original) (raw)

Triangulum Australe (abbeviation: TrA), the Southern Triangle, is a small constellation close to the southern circumpolar region and touched by the southern edge of the Milky Way. Its three leading stars are bright enough to serve as pointers to other constellations nearby, including Apus in the south, Norma in the north, Circinus in the west, and Ara and Pavo in the east. The open cluster NGC 6025 at the boundary with Norma, contains about 30 stars of seventh magnitude and fainter and is a good object for binoculars (distance 2,000 light-years; magnitude 5.1, diameter 12 arcminutes; RA 16h 03.7m, Dec –60° 20'.
