HIP 1191
Hot blue starWhat is HIP 1191
In the vast Whale burns a blue-white B-type star, whose surface exceeds ten thousand degrees. Its light crossed three hundred thirty-nine years to reach us, departing around 1687, the year Newton published his Principia Mathematica in London and refounded modern physics. Hotter, more massive, and far more luminous than the Sun, it lives a brief and dazzling existence, leaving its bluish mark upon the silent back of Cetus.
Where it is and when to see it
HIP 1191 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.
