18 Pegasi
Hot blue starWhat is 18 Pegasi
18 Pegasi is a hot blue-white B-type star, set just over a thousand light-years away in the autumn Pegasus. Its light left the surface in the High Middle Ages, long before telescopes had been invented. It belongs to the most energetic family in the catalogue: relatively short lives, hot atmospheres, and an almost electric blue that travels for centuries before brushing the Earth.
Where it is and when to see it
18 Pegasi lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
