Variable starWhat is HIP 22881
In Eridanus, the long celestial river, a yellow G-type variable star beats at about 278 light-years. Its light set out around 1748, as Linnaeus was finishing the foundations of the modern classification of living beings. It shares the Sun s spectral type, but its brightness shifts subtly over time, a reminder that even quiet stars carry an inner pulse in perpetual motion.
Where it is and when to see it
HIP 22881 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is December: 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.
