What is 12 Cassiopeiae

12 Cassiopeiae reaches us from 702 light-years away: the light we see today set out when the Normans were sailing toward Sicily. It is a hot, young blue-white B-type, perched on the unmistakable W of Cassiopeia. The vain queen, bound to her throne in punishment, wheels endlessly around the celestial north pole —and this star wheels with her, turn after turn.

Where it is and when to see it

12 Cassiopeiae 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.
