10 Andromedae
Cool red starWhat is 10 Andromedae
10 Andromedae is a cool red M-type giant, one of the reddest visible to the naked eye in its constellation. Its deeply warm, reddish light crosses 481 years to reach us —it set out when Cervantes was being born in Alcalá de Henares. It belongs to the family of old, swollen stars that have already left core hydrogen burning behind and move, slowly, toward the end.
Where it is and when to see it
10 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.
