HIP 12273
What is HIP 12273
In the W-shaped chair of Cassiopeia keeps watch a yellow sun, a G-type star slightly larger than ours whose light began its journey 256 years ago. When it set out, European workshops were refining the first steam engines that would reshape the world. At that distance, its glow reaches us already ancient, having crossed a century and a half of human history before touching the retina of anyone looking northward tonight.
Where it is and when to see it
HIP 12273 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.
