HIP 17584
Hot blue starWhat is HIP 17584
In the starry shoulder of Perseus burns a blue-white beacon 748 light-years away, sister to the young clusters of the region. Its light departed around 1278, when Alfonso X the Wise was compiling in Toledo the Alfonsine Tables that would guide centuries of astronomy. A hot B-type vibrates at twenty thousand degrees, so many that its light tears electrons from the gases around it.
Where it is and when to see it
HIP 17584 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
