HIP 49220
Hot blue starWhat is HIP 49220
In Leo, the lion's constellation, blazes a blue B-type star whose light has been crossing space for nearly a thousand years. When it set out, Islamic astronomers in Toledo and Baghdad were compiling the so-called Toledan Tables, the basis of eclipse calculations for centuries. Very hot and massive, several times more luminous than the Sun, it is a young incandescent star that lives fast. Its blue-white glow belongs to an era when Europe measured the heavens thanks to wisdom inherited from the Islamic world.
Where it is and when to see it
HIP 49220 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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.
