HIP 63117
Hot blue starWhat is HIP 63117
An O-type star —among the rarest and most violent in the universe— burns in Crux, the small Southern Cross that guides austral navigators. Its light crossed a dizzying distance, more than 326,000 light-years: it set out before Homo sapiens had even emerged and Neanderthals still walked across Europe. Tens of times more massive and hotter than the Sun, its blue-white blaze is the echo of a world older than humanity can remember.
Where it is and when to see it
HIP 63117 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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.
