Südliches Dreieck
Southern Triangle (Trianguli Australis)
Triangulum Australe, the Southern Triangle, is a small but distinctive constellation near Alpha Centauri in the southern sky. Created by Dutch navigators in the late 16th century, it forms a nearly equilateral triangle of three bright stars and is easily recognizable. Despite its small size, it offers fine deep-sky objects for southern observers.
📜 Mythologie
Triangulum Australe was created from observations by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman during their expedition to the East Indies (1595-1597). It was introduced by Petrus Plancius in 1598 and later included in Johann Bayer's 'Uranometria' (1603). The constellation provides a southern counterpart to the ancient Triangulum in the north. Its creation was part of the effort to fill the previously unmapped southern sky with new constellations.
