Along with Alpha and Beta Trianguli Australis it forms a prominent triangular asterism that gives the constellation its name (Latin for southern triangle).

[2] Based upon parallax measurements, Gamma Trianguli Australis is located at a distance of about 190 light-years (58 parsecs) from Earth.

[6] Its surface has an effective temperature of 8,225 K.[3] This is around 2,450 K hotter than the Sun[13] and gives it a white hue, typical of A-type stars.

The companion star would be a red dwarf with a mass of 0.15 M☉ and a semimajor axis of 1.8 AU.
