Theta Lupi
Hot blue starWhat is Theta Lupi
Theta Lupi is a blue main-sequence star spinning at a dizzying 331 km/s at its equator. That rotation deforms it: its equatorial diameter is roughly 15% larger than its polar one, a sphere flattened by its own momentum. At 415 light-years inside the Wolf, it is one of those hot, young beacons still in the bloom of its evolution.
Where it is and when to see it
Theta 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.
