HIP 45631
Hot blue starWhat is HIP 45631
Among the lateen sails that stitch the southern sky burns a blue B-type sun, a young and hot ember whose light set out 438 years ago. When its voyage began, Venetian shipyards were dragging Lepanto galleys ashore and the southern skies were still nearly untouched ground for Europe. Far more massive and luminous than our Sun, its bluish glow paints a clean, almost musical accent against the dark.
Where it is and when to see it
HIP 45631 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is March: 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.
