13 Andromedae
Variable starWhat is 13 Andromedae
13 Andromedae is a variable blue-white B-type star 300 light-years away in the autumn sky's chained princess. It joins the energy of hot atmospheres with the restlessness of subtle pulsations that only precision photometry can uncover. It glows near the great galaxy M31, that cosmic sister any pair of binoculars can find among the stars of Andromeda.
Where it is and when to see it
13 Andromedae lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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.
