HIP 18396
Hot blue starWhat is HIP 18396
In Perseus it burns with the cutting blue of hot class B stars, a light that betrays a nuclear furnace far superior to the Sun's. Its glow arrived after a 729-year journey: when it set out, the Christian kingdoms were advancing through the Iberian peninsula and the Mongols were finishing redrawing Asia under the descendants of Genghis Khan. It is a sun young on the cosmic scale, living intensely and making its presence felt even from several centuries of light away.
Where it is and when to see it
HIP 18396 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.
