HIP 109831
What is HIP 109831
Lacerta, the small Lizard stitched between Cygnus and Andromeda by Hevelius in the 17th century, hosts a white class A star. Its photon began the journey 268 years ago: it left when Linnaeus was finishing his Systema Naturae and European science was learning to classify everything it saw. This light, by contrast, still resists any proper name.
Where it is and when to see it
HIP 109831 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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.
