What is 12 Andromedae
12 Andromedae is a yellow-white F-type star in the body of the Princess, that long chain of stars stretching toward the great square of Pegasus. At 137 light-years its surface is somewhat hotter than the Sun's, and its magnitude 5.77 makes it a subtle but achievable spark under clean skies. The light arriving tonight set out in the late 19th century, when great refractors were beginning to photograph the sky on dry plates.
Where it is and when to see it
12 Andromedae 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

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.
