HIP 21819
What is HIP 21819
Above the bull's shoulders, deep in Taurus, shines a white class A star some 381 light-years away. Its light set out around 1644, the year Descartes published his Principia philosophiae and laid the foundations of a new mechanistic physics. Hot and crystalline of glow, it is one of those beacons that quietly watched humanity change its way of thinking about the cosmos during the scientific revolution.
Where it is and when to see it
HIP 21819 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.
