HIP 1728
Variable starWhat is HIP 1728
A vast red M-type giant glows within the figure of Cetus, the celestial whale, breathing in slow pulsations of light. Far cooler than the Sun yet hundreds of times its size, its glow began this voyage almost nine centuries ago, when Gothic cathedrals were rising across Europe and astronomy still travelled in Arabic manuscripts. Across 882 light-years its red breathing arrives tonight, a slow heartbeat older than most stones standing in any city of the world.
Where it is and when to see it
HIP 1728 lies in the southern 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.
