HIP 636
What is HIP 636
The Whale, Cetus, that great sea-monster of the equatorial sky, harbours this white A-class star. Its light departed around 1770, the year Tiepolo died in Madrid and the teenage composer Mozart made his first public appearances in Italy. More than two and a half centuries later, that white glow crosses the monster's back and lands in our sensors.
Where it is and when to see it
HIP 636 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.
