What is Mu Piscis Austrini

Mu Piscis Austrini shines at 136 light-years in the constellation of the Southern Fish, the same modest sky that holds Fomalhaut. It is a white A2 main-sequence star with an effective temperature of 8,541 K, placing it among the cousins hotter than the Sun. It moves through the galaxy at about 20 km/s, on a wide orbit that will carry it between 23,800 and 28,500 light-years from the centre of the Milky Way.

Where it is and when to see it

Mu 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
