HIP 107129
Variable starWhat is HIP 107129
A white A-type star shines faintly within the rich starfields of Cygnus, hotter and more luminous than the Sun, its brightness wavering in slow, almost imperceptible pulsations. Its light has been travelling for more than two thousand years, beginning when Eratosthenes was measuring the circumference of the Earth from the shadows in two Egyptian wells. After 2,039 light-years, that pale, breathing glow arrives tonight as a quiet message from the dawn of measurement itself.
Where it is and when to see it
HIP 107129 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.
