68 Cygni
Variable starWhat is 68 Cygni
68 Cygni is a rare specimen: a massive blue O-type star, one of the hottest and most luminous classes in existence, burning at tens of thousands of degrees at its surface. It belongs to Cygnus, that cross laid out across the Milky Way, and is tied to the young stellar associations populating the region. Its brightness varies slightly, an echo of the violent processes that stir blue giants.
Where it is and when to see it
68 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 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
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.
