ATRIA (Alpha Trianguli Australis). Among the easiest constellations to invent are simple triangles. There are two of them, one north (Triangulum) and one far south (Triangulum Australe).
[8205] alpha Trianguli, the second brightest star, is a spectroscopic binary lying about 64.1 light-years from Earth. It is also known as Mothallah or Rasal Muthallah and Caput Trianguli, both meaning "the head of the triangle.
It lies in the north central part (2:17:3.2:+34:13:27.2, ICRS 2000.0) of Constellation Triangulum, the Triangle -- near Gamma and 7 Trianguli, slightly southeast of Beta Trianguli and northeast of Mothallah (Alpha Trianguli) and Hamal ...

Its brightest star is named Atria (for alpha Trianguli Australis), in the manner of Acrux in the Southern Cross. It is easily seen near α and β Centaurus. Crux and Musca have their own pages.
The three main stars of Triangulum Australe are brighter than those of their northern counterpart, although the constellation is smaller. Navigators have named its brightest star Atria, a contraction of its scientific name Alpha Trianguli Australis.
