Beta Coronae Australis
What is Beta Coronae Australis
Beta Coronae Australis is an orange giant that has burned through the hydrogen in its core and swollen to 39 times the Sun's diameter. It shines with more than 600 solar luminosities and carries a rare abundance of cyanogen in its atmosphere—a chemical fingerprint that marks it as a CN star to spectroscopists. It crowns the small southern arc the ancients called the Southern Crown, 474 light-years away.
Where it is and when to see it
Beta Coronae Australis lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
