Tonatiuh
What is Tonatiuh
Tonatiuh takes its name from the Mexica sun god, in the IAU campaign that assigned Mesoamerican names to stars hosting planets. It is a yellow giant in Camelopardalis, the celestial giraffe, one of the emptiest constellations in the northern sky. At 317 light-years, its golden light crossed space over the same span in which three centuries of human civilisations followed one another, without it varying its brightness in any noticeable way.
Where it is and when to see it
Tonatiuh lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: 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.
