58 Hydrae
What is 58 Hydrae
58 Hydrae is an orange giant adrift 331 light-years away, in the endless tail of Hydra, the longest constellation of the sky. It belongs to that family of mature suns that have left quiet hydrogen fusion behind and swollen into cool, lantern-bright orbs. Its amber tone stands out against the blue of nearby giants. Its light, dispatched around 1694, reaches us just as we stop looking up.
Where it is and when to see it
58 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 May: 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.
