HIP 45581
What is HIP 45581
In Carina, the keel of the ancient ship Argo, shines a white A-type star whose light set out around 1675, the year Charles II founded the Royal Observatory at Greenwich. Hotter and more luminous than the Sun, it wears the pure white of stars still living their youth. Its light crossed three and a half centuries to meet the moment in which we now look upon it, cold and exact.
Where it is and when to see it
HIP 45581 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.
