52 Hydrae
Hot blue starWhat is 52 Hydrae
52 Hydrae burns blue at nearly four hundred light-years, one of the hot stars scattered along the reaches of Hydra, the sky's largest and longest constellation. Its light set out when European astronomers had not yet invented the modern refracting telescope. Faint to the naked eye, its B spectral class reveals a surface temperature far above that of the Sun and a stellar life destined to be brief and luminous.
Where it is and when to see it
52 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.
