Psi 3 Aquarii
What is Psi 3 Aquarii
Psi-3 Aquarii is a blue-white visual binary whose surface reaches nearly ten thousand degrees—almost twice the Sun's temperature. The pair contributes some seventy solar luminosities to the night sky, and lives within Aquarius, the ancient constellation pictured pouring water from a tilted urn down toward the Southern Fish. Its combined light travels 262 years through the dark before brushing the human eye, faint but unmistakable.
Where it is and when to see it
Psi 3 Aquarii lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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.
