What is Epsilon Trianguli Australis

ε Triangulum Australe shines coppery at 202 light-years, set within the small Southern Triangle first charted by Spanish and Portuguese sailors rounding the Cape of Good Hope. A K-class orange giant, it is a mature star whose atmosphere has swollen and cooled into that warm hue. It rests at one corner of this tight, almost geometric figure cut into the heart of the southern Milky Way, far below the horizon of any northern observer.

Where it is and when to see it

Epsilon 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.
