Hot blue starWhat is HIP 103312
In the direction of Cygnus lies a blue B-type star, intensely hot and supergiant by nature. Its distance, estimated in hundreds of thousands of light-years, suggests it belongs more to the halo than to the galactic disc: its light reaches us after a millennial journey that began long before any human civilisation. It is a bluish beacon linking the celestial swan with remote extragalactic regions.
Where it is and when to see it
HIP 103312 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
