What is Xuange

Xuange shines 99 light-years away in Boötes, a white class-A star whose name comes from traditional Chinese astronomy. It means roughly «the shadowed pavilion» and belonged to the imperial constellations that organised the court's sky. The Western Boötes, the herdsman who follows the Great Bear, coexists here with the eastern cartography: two ways of reading the same strip of sky, neither more true than the other, only different in grammar.

Where it is and when to see it

Xuange lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is March: 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

Write my signature

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.
