59 Persei
What is 59 Persei
59 Persei is a suspected astrometric binary —an apparently single star whose motion across the sky betrays the gravitational tug of an unseen companion. Of class A1Vn, it is a blue-white main-sequence star roughly 256 light-years away, riding the shoulders of Perseus. The «n» in its spectral type marks broadened lines: it spins fast, and its atmosphere carries the smeared signature of that rotation.
Where it is and when to see it
59 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 December: 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.
