HIP 55597
Hot blue starWhat is HIP 55597
In tiny Musca, a modern constellation of the southern sky, glows a blue B-type star at 403 light-years —far enough that its light departed when Newton published the «Principia» in 1687. It is a blue-white furnace several times hotter than the Sun, stitched to an austral corner that Renaissance European navigators named while charting southern skies for the first time.
Where it is and when to see it
HIP 55597 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
