Gamma Persei
Variable starWhat is Gamma Persei
Gamma Persei keeps watch in the northern heart of Perseus, a yellow G-type giant whose light —dispatched 243 years ago— now arrives with a subtle wink. It belongs to the rare club of long-period eclipsing binaries: every fourteen years, an unseen companion drifts across its face and dims it briefly, an event astronomers await like a returning comet. A quiet star in a constellation crowded with louder names.
Where it is and when to see it
Gamma Persei lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
