Xi 2 Centauri
Hot blue starWhat is Xi 2 Centauri
Xi-2 Centauri is a blue triple system 467 light-years away, with an inner pair orbiting in just seven and a half days and a third, cooler companion sitting twenty-five arcseconds away. The primary is a B1.5 star carrying eight solar masses and shining with 1,700 times the Sun's luminosity at nearly 21,000 kelvin. The inner binary was discovered in 1910 by American astronomer Joseph Haines Moore.
Where it is and when to see it
Xi 2 Centauri lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
