What is 15 Orionis
15 Orionis is a yellow-white F-type star set on the northern reaches of the Hunter, around 538 light-years from us. Its surface runs somewhat hotter than the Sun's, and seen from Earth as a magnitude 4.81 spark, it must be intrinsically very luminous to reach so far. The light now settling into a human eye left that atmosphere when Europe was still drawing its first modern charts of the heavens.
Where it is and when to see it
15 Orionis 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
