HIP 47391
Hot blue starWhat is HIP 47391
Deep in the southern reaches of Carina burns a blue-white B-type sun, fierce and youthful, far hotter than our own star. Its light set out for Earth around 226 years ago, when the French encyclopedists were kindling the fires of reason and cabinets of curiosities were beginning to map the sky. That glow has spent more than two centuries on the road to arrive at the exact instant someone looks up.
Where it is and when to see it
HIP 47391 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.
