HIP 33421
What is HIP 33421
Gemini, the eternal twins of the winter sky, hides a yellow G-type star —of solar tone— at 422 light-years. Its light departed around 1604, the year Kepler was observing the appearance of the supernova that would bear his name, the last naked-eye stellar explosion in the Milky Way. While astronomy was living a historic moment, this star was dispatching the light now arriving at magnitude 5.91.
Where it is and when to see it
HIP 33421 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: 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.
