HIP 90806
Hot blue starWhat is HIP 90806
Sagittarius aims toward the heart of the galaxy, and in its arrow burns this blue-white type B star, scorching beyond most. The light betraying her tonight set out 223 years ago, when Lavoisier was naming oxygen and modern chemistry was being born in Paris. Hot-blue stars like this burn so fast that the word «eternal» loses its meaning beside them.
Where it is and when to see it
HIP 90806 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
