HIP 15643
What is HIP 15643
Along the long course of the river Eridanus flows a yellow G-type star, mild sister of our Sun. Its light departed three hundred and sixty-seven years ago, when Christiaan Huygens built the first pendulum clock and split time into exact seconds. Of warm, familiar glow, it looks like a household fire hung from the celestial current. To see it is to remember that in that century humankind, at last, learned to measure itself.
Where it is and when to see it
HIP 15643 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
