What is HIP 81304

On the curling tail of Scorpius glows an orange K-type ember. Its light set out almost three hundred and forty-three years ago, while Newton was publishing the «Principia» and rearranging the cosmos with three laws. Cooler and calmer than the Sun, it still seems to hold the hush of that silent revolution. To watch it tonight is to peer into an age when the universe first began to obey equations.

Where it is and when to see it

HIP 81304 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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

Write my signature

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.
