Zeta Herculis
Nearby starWhat is Zeta Herculis
Zeta Herculis shines from just 35 light-years away, a luminous neighbour at the heart of the celestial Hero. Yellow-white like a Sun grown slightly older, its light reaches us across a distance a photon crosses in barely three and a half decades. To watch it is to look upon one of the rare bright stars close enough that the cosmos, for a moment, feels like a neighbourhood.
Where it is and when to see it
Zeta 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 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.
