Gamma Horologium
What is Gamma Horologium
Gamma Horologii is a yellow G-type star about 183 light-years away, set in the small Clock constellation that Lacaille named in the eighteenth century to honour the precision of pendulum clocks. It is an older sibling of the Sun, already somewhat evolved, with a luminosity several times that of our own star. Its quiet brightness slips easily unnoticed among the more spectacular southern constellations, but it belongs to that silent family of yellow stars that offer the best possible mirror for imagining the Sun's future.
Where it is and when to see it
Gamma Horologium lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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.
