HIP 22157
What is HIP 22157
In Orion, the eternal hunter of the northern winter, shines a white A-type star, hotter and more luminous than the Sun, with the bright purity only young stars possess. Its light takes around 235 years to cross the void: what arrives today departed about 1791, while French revolutionaries were drafting their first Constitution and Mozart was composing The Magic Flute. Orion presides over those skies like a myth still alive.
Where it is and when to see it
HIP 22157 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is December: 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.
