Psi 1 Lupi
What is Psi 1 Lupi
Psi-1 Lupi belongs to an optical pair alongside Psi-2 Lupi: two yellowish points that a sharp eye can separate on a dark night, though they do not truly share origin or motion. It is an evolved yellow giant, similar in temperature to the Sun but far larger and more luminous. From 220 light years away, it offers a portrait of what yellow stars become when they enter their maturity.
Where it is and when to see it
Psi 1 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.
