What is 100 Herculis
100 Herculis is a white A-type star lying just over one hundred and twenty-five light-years away, a relatively close distance in galactic terms. Its light departed around the late nineteenth century, when astronomical photography was beginning to transform how the sky was charted. It dwells in Hercules, the great mythological figure of the northern summer sky, where it keeps company with constellations as renowned as nearby Lyra and its brilliant Vega.
Where it is and when to see it
100 Herculis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
