22 Orionis
Hot blue starWhat is 22 Orionis
22 Orionis is a B-type blue star 929 light-years away, set in the shield of Orion within that band of hot suns belonging to the immense Orion OB1 association. It shares its lineage with Rigel and the Belt stars —young molecular clouds that have been igniting massive suns for only a few million years. Its light took nearly a millennium to cross the void to the eyes that meet it tonight.
Where it is and when to see it
22 Orionis lies in the southern 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.
