11 Cepheus
What is 11 Cepheus
11 Cephei is a young orange giant —barely 670 million years old— already over twice the Sun's mass and swollen to twelve times its radius. With a 4.620-degree surface and sixty-one times the solar output, it lights a quiet corner of Cepheus from 182 light-years away. Its fate is plain: a planetary nebula waits on the cosmic horizon, and beyond it the crystalline silence of a white dwarf.
Where it is and when to see it
11 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

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.
