Pi 1 Hydrus
Cool red starWhat is Pi 1 Hydrus
Pi-1 Hydri is a red M-type giant at more than seven hundred and seventy light-years in the Male Water Snake, that small southern serpent added to the sky by Dutch navigators near the south pole. Its deep reddish tone betrays a vast, cool atmosphere already in the final phases of its evolution. A slow ember in a corner of the sky where almost no other legends touch it.
Where it is and when to see it
Pi 1 Hydrus 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.
