HIP 5566
Hot blue starWhat is HIP 5566
In Cassiopeia, the queen enthroned in the northern sky, shines a blue-white B-type star, young and far hotter than the Sun. Its light left its surface around 405 years ago, when Kepler had just published the laws of planetary motion and blown-glass telescopes were beginning to multiply the visible sky. It arrives now on time, with the sharp edge that defines a bluish sun.
Where it is and when to see it
HIP 5566 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
