What is Upsilon Piscis Austrini

υ Piscis Austrini pours an orange glow from 424 light-years, in the body of the Southern Fish — one of the oldest constellations recorded by the Babylonians. A K-class giant, swollen and cool by stellar standards, it shares its patch of sky with the luminous Fomalhaut without sharing its fame. When this light left its atmosphere, the Peace of Westphalia was being signed in Europe.

Where it is and when to see it

Upsilon 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
