What is Beta Mensa

Beta Mensae burns some 794 light-years away, distant even by the standards of its modest southern constellation. It is a yellow G-type star, a kind of aged Sun whose envelope has swollen well beyond the solar size; what we see today as a faint point left its surface in an era preceding the first telescopic observations.

Where it is and when to see it

Beta Mensa lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
