What is Tianyi
Tianyi is an orange giant in Draco, its name taken from classical Chinese astronomy: «Tian Yi» designated a celestial deity linked to the imperial court of the sky. At 741 light-years, it shines right at the edge of what the unaided eye can distinguish under a truly dark sky. It is a quiet reminder of how many stars with proper names remain hidden from those who watch from a lit city.
Where it is and when to see it
Tianyi lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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.
