Upsilon Grus
What is Upsilon Grus
Upsilon Gruis is a double in the Crane whose components are separated by more than a degree on the sky —an enormous gap for a stellar pair—, with a marked difference in brightness between the two. The primary is a white main-sequence star, young and hot, set at 285 light-years inside one of the southern constellations charted by Dutch navigators.
Where it is and when to see it
Upsilon Grus lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
