HIP 18081
Hot blue starWhat is HIP 18081
In the depths of Perseus burns a hot blue B-class star, lying some eight hundred and forty light-years away. The sharp light that now defines it set out around 1185, when the first windmills were rising in Europe and the Latin Middle Ages were approaching their intellectual noon. Its blue tone, far hotter than the Sun's yellow, places it among the young, massive and short-lived stars.
Where it is and when to see it
HIP 18081 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.
