HIP 57841
What is HIP 57841
Across the long back of Hydra shines an F-class star, yellow-white and somewhat hotter than the Sun, just over a hundred light-years away. The light that now defines it set out as Europe was sinking into the First World War and the first radios were beginning to weave the continent together with distant voices. Its pearly tone belongs to those stars that sit between the Sun's yellow and the white of hotter classes, in a serene balance.
Where it is and when to see it
HIP 57841 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
