What is 30 Cepheus

30 Cephei is a white A-type star about 287 light-years away, set in the circumpolar region ruled by the angular silhouette of the King. Hotter and whiter than the Sun, its surface burns somewhere between 8,000 and 10,000 degrees. The light arriving now left around 1739, in the heart of the Enlightenment, when the great refractors were beginning to chart the northern sky.

Where it is and when to see it

30 Cepheus lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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

Write my signature

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.
