80 Pegasi
Variable starWhat is 80 Pegasi
80 Pegasi is a variable red giant, swollen to roughly seventy-one solar radii, about 845 light-years away in the night-time stables of the Winged Horse. Its brightness shifts with the slow cadence of cool giants that have left their youth behind. Its crimson tone is unmistakable through a telescope: a vast suspended ember whose light —released around the twelfth century— has only just crossed Earth's atmosphere to reach a pair of eyes.
Where it is and when to see it
80 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 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

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.
