HIP 22913
Hot blue starWhat is HIP 22913
In splendid Orion, beside the most famous stars of the winter sky, a blue B-type star burns about 364 light years away. Its light departed around 1662, the year the Royal Society of London was founded and modern science gained one of its institutional pillars. Far hotter than the Sun and of intense bluish-white, it fits into that fellowship of young and powerful stars that gives the constellation its unmistakable character. It shines quietly near the hunter, stitched into the great stellar tapestry.
Where it is and when to see it
HIP 22913 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is December: 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.
