HIP 20241
What is HIP 20241
In Perseus glows an orange K-type star, cooler than the Sun and dressed in a deep gold. Its 402 light-years set out while Galileo was defending his heliocentrism before the Holy Office and scientific freedom played its first great public hand. That light — serene today — was contemporary with a trial that would forever change the relationship between knowledge and authority.
Where it is and when to see it
HIP 20241 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.
