Psi 3 Aurigae
Hot blue starWhat is Psi 3 Aurigae
Psi-3 Aurigae is a blue giant about 1,371 light-years away, in the Charioteer, a B8 III star that radiates one thousand six hundred times the Sun's light from only four times its radius. It spins at 118 km/s, and at more than thirteen thousand degrees on its surface it belongs to that lineage of hot stars that live fast, burn their mass violently and leave few generations behind.
Where it is and when to see it
Psi 3 Aurigae 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.
