HIP 102358
Variable starWhat is HIP 102358
In the depths of Cepheus, the mythical king of the northern sky, beats a red M-type giant 1098 light-years away. Its variable light set out when the Vikings were founding settlements in Iceland and Greenland, tracing unprecedented Atlantic routes. Cooler than the Sun yet enormous, it swells and shrinks its atmosphere in a slow, deep rhythm. It is a red and ancient voice, a whisper that travelled a thousand years for us to hear it as light.
Where it is and when to see it
HIP 102358 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.
