What is 21 Piscis Austrini
21 Piscis Austrini shines in the Southern Fish, that small southern constellation dominated by the solitary beacon Fomalhaut. It is a yellow G-type star some 323 light-years away, a spectral sister of the Sun but more luminous because of a more evolved stage. Its light set out around 1703, just entering the eighteenth century, while Europe was establishing its first modern scientific academies.
Where it is and when to see it
21 Piscis Austrini lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
