Eta 2 Coronae Australis
Hot blue starWhat is Eta 2 Coronae Australis
Eta-2 Coronae Australis is a solitary blue-white B9 subgiant with 3.2 solar masses and 171 times the Sun's luminosity, about 482 light-years away within the Southern Crown. At 213 million years it remains young on a stellar scale, burning at nearly 11,000 kelvin. It shines within the small austral ring symmetrical to the northern Corona, a discreet garland at the feet of Sagittarius.
Where it is and when to see it
Eta 2 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.
