47 Librae
Hot blue starWhat is 47 Librae
47 Librae is a hot blue B-type star on the pans of the Scales, about 771 light-years away. Its light left around the 13th century, when Gothic cathedrals were rising across Europe. B-type stars shine with a crisp, almost steely light; in a constellation often dim like Libra, that cold tone is especially recognisable to anyone who knows how to read the colour of stars.
Where it is and when to see it
47 Librae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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.
