Chi 1 Hydrae
What is Chi 1 Hydrae
Chi-1 Hydrae is a yellow-white subgiant 141 light-years away, in the long winding body of Hydra. About 1.3 billion years old, it burns at 6,600 kelvin, a little hotter than the Sun. It is a binary, paired with a quieter companion that travels with it through the galaxy. It marks the western reaches of Hydra, where the celestial serpent rises just beneath Cancer.
Where it is and when to see it
Chi 1 Hydrae lies in the southern 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

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.
