HIP 90637
Hot blue starWhat is HIP 90637
In the kneeling silhouette of Hercules burns a blue B-class star, whose light set out some 1,226 years ago, when Charlemagne was being crowned Emperor of the West in St Peter's Basilica. B stars are massive, swift furnaces; they burn their fuel in a hurry and, in less time than the laws of the cosmos seem to allow, collapse as supernovae.
Where it is and when to see it
HIP 90637 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
