Omicron Cassiopeiae
Variable starWhat is Omicron Cassiopeiae
Omicron Cassiopeiae is a bluish B-type giant some 703 light-years away, a hot, massive star whose stellar wind can carve disks of gas around it. It belongs to the family of so-called Be stars, known for variability tied to the forming and dispersing of these disks. Its light pulses, subtly, within the great W traced by Queen Cassiopeia across the northern sky.
Where it is and when to see it
Omicron 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 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.
