HIP 82129
Variable starWhat is HIP 82129
The Southern Triangle holds this white A-class star, a variable whose brightness oscillates to a rhythm of its own, only revealed by long records. The light now crossing our atmosphere left the star around 1328, when Marco Polo had returned from Cathay and Europe was entering its last medieval century. Six and a half centuries of travel for a white dot in the southern sky, inside a constellation invented by Renaissance navigators.
Where it is and when to see it
HIP 82129 lies in the southern 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.
