HIP 15770
Variable starWhat is HIP 15770
In Perseus, hero of the winter sky, a variable blue B-type star shines about 542 light-years away. Its light set out around 1484, while in Florence Botticelli was painting «The Birth of Venus» and the Medici sustained the Quattrocento. Its slow pulse and bluish hue speak of an incandescent youth, far hotter than the Sun.
Where it is and when to see it
HIP 15770 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.
