What is HIP 27939

In Orion, the most recognisable hunter of the winter sky, shines an orange K-type star, cooler than the Sun yet noticeably more luminous due to its size. Its light took roughly 875 years to cross space: it set out around 1150, at the height of European Romanesque, when Notre-Dame de Paris and the first universities of Bologna and Oxford were beginning to rise. That patient amber now vibrates beside the hunter.

Where it is and when to see it

HIP 27939 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

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.
