Variable starWhat is Tejat
Tejat is a red giant variable in Gemini, 231 light-years away, cool and enormous as almost all stars at the dusk of their lives. Its name comes from Arabic and is associated with the idea of treading, in allusion to the foot of the twin Castor. Its brightness breathes with the slowness of months; each pulse is a layer of hydrogen fused in its ancient heart.
Where it is and when to see it
Tejat lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is December: 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
