55 Orionis
Hot blue starWhat is 55 Orionis
55 Orionis is a blue B-type star about 1049 light-years away, in the rich territory of the Hunter where hot, young stars cluster thickly. It is also catalogued as an infrared source with mild variability; its brightness hovers right at the edge of unaided sight. Its light departed around the year 1000, crossing the late Middle Ages, the Renaissance and modernity before touching our instruments.
Where it is and when to see it
55 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.
