Delta Trianguli Australis
What is Delta Trianguli Australis
Delta Trianguli Australis is a yellow G-type giant, anchored in the Southern Triangle some 607 light-years away. It shares its spectral class with the Sun, yet has swollen far beyond, becoming one of the warm yellow embers that sign that small triangle of the southern sky, a constellation drawn by European navigators as they crossed the equator toward newly mapped seas. Its mild light, modest to the unaided eye, has travelled for more than six centuries before reaching the night from high in the southern hemisphere.
Where it is and when to see it
Delta 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 June: 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.
