What is Beta Trianguli Australis

Beta Trianguli Australis shines as the brightest jewel of the small Southern Triangle, a constellation that only reveals itself from southern latitudes. Just 40 light-years away, it is an F-type subgiant that has already begun to swell after burning through the hydrogen in its core. Its golden-white light crosses a distance roughly nine times that of Vega, and watching it is to glimpse the fate awaiting the Sun several billion years from now.

Where it is and when to see it

Beta 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.
