9 Cepheus
Variable starWhat is 9 Cepheus
9 Cephei is a blue B-type variable kindled in the northern reach of the sky, within the constellation that outlines the silhouette of King Cepheus. Its glow is not steady: it pulses with the restless rhythm typical of massive stars, those young suns that burn faster and die sooner. Its light crosses space for hundreds —perhaps thousands— of years before surfacing as a bluish point among the northern circumpolar stars.
Where it is and when to see it
9 Cepheus 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.
