What is HIP 21297

Along the channel of Eridanus drifts this orange K-type giant, whose light has spent more than seven hundred and sixty years crossing the void. It set out around 1265, when Thomas Aquinas was writing his Summa Theologiae and Marco Polo had not yet departed for Cathay. Cooler than the Sun, its coppery tone suggests old embers and endless sunsets. It reaches us as an orange echo of the Middle Ages, kindled in the longest river of the southern sky.

Where it is and when to see it

HIP 21297 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

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.
