What is 21 Piscium
21 Piscium is a white A-type star in the Fishes, about 304 light-years away from Earth. Pisces traces two long threads tied together just south of the Great Square of Pegasus, and among its faint stars this A-type clearly stands out for its clean, bluish tone. Pisces also harbours the vernal point —the abstract mark where the Sun crosses the celestial equator each Northern Hemisphere spring.
Where it is and when to see it
21 Piscium lies in the northern 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
