Gamma Trianguli Australis
What is Gamma Trianguli Australis
Gamma Trianguli Australis is one of the three vertices that trace the Southern Triangle, a sharp asterism of the deep austral sky. A white A-type star, its light takes around 184 years to cross the void to us. It anchors a luminous trio that has guided southern navigators since long before Europe learned to name those skies.
Where it is and when to see it
Gamma Trianguli Australis lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
