HIP 17798
What is HIP 17798
In Eridanus, already far south of its source, glows an orange K-type star. Its light has been travelling for 593 years: it set off around 1432, the very year the Portuguese discovered the Azores islands in their Atlantic advance. Cooler than the Sun, it appears in the celestial river like a discreet lantern, held up by the current of its own constellation.
Where it is and when to see it
HIP 17798 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
