Theta Pyxidis
Cool red starWhat is Theta Pyxidis
θ Pyxidis pours a reddish glow from 503 light-years, set within the small southern Compass that Lacaille named for the navigator's instrument of the eighteenth century. It is an M-class giant, an immense and cool star whose swollen surface gives it that fiery hue and announces, in slow stellar terms, the late chapters of its life. When this light first slipped from its atmosphere, Newton's Principia had not yet been published on Earth.
Where it is and when to see it
Theta Pyxidis lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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.
