HIP 97757
Hot blue starWhat is HIP 97757
In Cygnus burns another star of the rare O class, a blue supergiant of magnitude 5.6 that rises in the summer nights of the northern hemisphere. It is one of the hottest and most luminous bodies accessible to a trained eye under deep skies, thousands of times more radiant than the Sun and with a surface temperature several times the solar value. It belongs to the select group of stars that trace the visible contours of the galactic spiral arms.
Where it is and when to see it
HIP 97757 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
