HIP 11840
What is HIP 11840
At 271 light-years, in the modest northern Triangle, blazes an orange giant whose light set out in the late eighteenth century, when William Herschel discovered Uranus and doubled the known size of the solar system. Cooler and larger than the Sun, its amber tone marks a mature star. It inhabits a small, almost minimalist constellation, drawn by three modest stars in the autumn sky.
Where it is and when to see it
HIP 11840 lies in the northern 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.
