What is 30 Cygni

30 Cygni is a white A-type star burning 611 light-years away, near the heart of the Swan. It belongs to the Northern Cross, the asterism that spreads its wings across the summer Milky Way. With no known companion or pulsation, its light is a steady flame —the glow of a young, hot sun many times more luminous than our own.

Where it is and when to see it

30 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.
