Koeia: the deep red star of Eridanus
deep red · Eridanus · HIP 12961
Koeia is a deep red star in the constellation Eridanus, one of the few thousand stars bright enough to carry an officially recognised name. It rewards a pair of binoculars on a clear night.
Most stars in the sky are anonymous points of light. Koeia is not — it has held a name across generations of sky-watchers, which makes it a rare thing to attach a name of your own to.
