Iota Trianguli Australis
Variable starWhat is Iota Trianguli Australis
Iota Trianguli Australis is a variable F-type star 127 light-years away, set within the compact Southern Triangle. Its light does not hold perfectly still: it pulses with the subtle rhythm of a yellow-white star crossing an instability strip. The constellation, one of the crispest figures of the southern sky, was traced by Dutch navigators as an austral counterpart to the older northern Triangle and is recognised by its near-geometric outline.
Where it is and when to see it
Iota 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.
