89 Herculis
Variable starWhat is 89 Herculis
89 Herculis is a yellow type-F variable, one of the most remote stars catalogued within the figure of Hercules, where such an extreme distance suggests it belongs to the far regions of our Galaxy. Its brightness drifts slowly, hinting at a restless atmosphere. The light reaching us tonight has travelled across a span of time far longer than all of recorded human history.
Where it is and when to see it
89 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.
