HIP 104105
Hot blue starWhat is HIP 104105
In Cepheus gleams a blue B-type star, far hotter and more massive than the Sun. Its light took some 403 years to cross the void: it set out around 1622, when Kepler was publishing his final planetary tables and the Thirty Years' War was setting central Europe ablaze. That bluish fire, youthful and fierce on stellar scales, now adorns the silhouette of the king chained to the celestial north pole.
Where it is and when to see it
HIP 104105 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.
