20 Cygni
What is 20 Cygni
20 Cygni is an orange giant in the Swan, swollen past a dozen solar radii and shining some fifty times brighter than our star. Its tone is warm, deep amber, just over two hundred light-years out. When the light now slipping into the atmosphere set off, the European Baroque was at its height and nobody yet suspected that warm dot was so unreachably far.
Where it is and when to see it
20 Cygni lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
