Variable starWhat is HIP 84500
In Ophiuchus, the serpent bearer, pulses a variable blue-white B-class star whose light set out around 1372, during the Western Schism with two opposing popes. Its brightness does not hold still: it oscillates slowly, as if the star itself were breathing calmly. Far hotter and more massive than the Sun, it offers a cool, subtle glow, true to those young stars that live in haste and leave a luminous echo across the sky out of all proportion to their visible size.
Where it is and when to see it
HIP 84500 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
