33 Hydrae
What is 33 Hydrae
33 Hydrae shines with the orange light of a K-class star about 566 light-years away, in the long serpentine body of Hydra. Its golden tone reveals a surface cooler than the Sun s, while its distance and apparent brightness suggest a body of respectable size. The radiation crossing our sky tonight left in the mid fifteenth century, around the time of Gutenberg s printing press.
Where it is and when to see it
33 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 February: 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.
