HIP 90497
Hot blue starWhat is HIP 90497
In Serpens, the snake held by Ophiuchus high in the summer sky, burns a blue B-type star, far hotter and more massive than the Sun. Its light took roughly 708 years to cross the void: it departed in the early 14th century, when Dante was completing the «Divine Comedy» and Europe was living under the chill of the late Middle Ages. A blue pulse, ancient and fierce, traces the serpent's scales.
Where it is and when to see it
HIP 90497 lies in the northern 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.
