Xi 2 Lupi
Hot blue starWhat is Xi 2 Lupi
Xi-2 Lupi is a blue-white double B9-type star, 150 light-years away, in the constellation of the Wolf. About 381 million years old, it carries 2.4 solar masses and burns at nearly 10,000 kelvin, shining with around ten solar luminosities. It belongs to a region of the southern sky where the Wolf eternally chases the Centaur, two ancient figures sharing skies far from the busy zodiacal road.
Where it is and when to see it
Xi 2 Lupi lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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.
