Pi Ceti
Hot blue starWhat is Pi Ceti
Pi Ceti is a blue B-type star in the head of Cetus, the sea monster Perseus confronted to save Andromeda. At 393 light-years, its surface boils at temperatures far higher than the Sun's and pours much of its light into the invisible ultraviolet. Beneath the winter sky, its discreet yet piercing glow peers out from the mythological folds of the celestial whale.
Where it is and when to see it
Pi Ceti lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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.
