Lambda Cancri · Cancer
Hot blue starWhat is Piautos
Piautos, a hot and luminous blue star, shines in the northern claw of the Crab, in a constellation that ancient Chinese astronomers identified with a wandering ghost trapped in the winter sky. It is far: 458 light-years, in a modest but ancient corner of the heavens. The faint light crossing the firmament tonight set out in the late sixteenth century, when Tycho Brahe was observing the supernova that would change astronomy forever.
Where it is and when to see it
Piautos lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: 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.
