What is Miaplacidus
Miaplacidus is a white giant resting on the keel of the ancient ship Argo, now charted as Carina. Some 113 light-years away, its calm white glow reaches us from a relatively recent past: what we see tonight set out when the first great reflecting telescopes were reshaping modern astronomy. Its hybrid Arabic-Latin name suggests «placid waters», a fitting epithet for a steady, unflickering star of the southern sky.
Where it is and when to see it
Miaplacidus 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.
