What is 31 Cepheus

31 Cephei is a yellow-white F3 subgiant, about 3.7 times the Sun's radius and twenty-five times its luminosity. It burns at 6,700 K in the constellation named for the Ethiopian king, father of Andromeda in the Greek myth. It lies 179 light-years away: an intimate distance on galactic terms, near enough that its light crosses the void in less than two human lifetimes.

Where it is and when to see it

31 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 November: 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.
