29 Cygni
Variable starWhat is 29 Cygni
29 Cygni inhabits a rich stretch of the Swan, along the long axis that traces the bird in mid-flight across the night. It is a white A-type variable star about 139 light-years away —close enough for the ESA Hipparcos mission to have measured its luminous pulse with exquisite precision. Its light, dispatched in the first half of the 20th century, arrives today with the calm heartbeat of a young sun.
Where it is and when to see it
29 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

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.
