What is HIP 109471

On the neck of Pegasus glows an aged M-type red giant 681 light-years away. Its light began its journey around 1345, in the years immediately before the Black Death reached Europe. Much cooler than the Sun and enormously bloated by age, it is a reddish ember that seems to burn slowly along the flank of the winged horse.

Where it is and when to see it

HIP 109471 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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.
