HIP 104642
Hot blue starWhat is HIP 104642
Far beyond the usual limits, in the direction of Cepheus, looms a colossal blue star at hundreds of thousands of light-years away. Its light reaches us from an era when the first modern humans had not yet walked across Africa: it travelled through galaxies and vast silences. So hot and luminous it belongs to the handful of stars able to illuminate entire volumes of the deep cosmos.
Where it is and when to see it
HIP 104642 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
