Acamar
Acamar: the white star of Eridanus
white · Eridanus · θ Eri
Acamar is a white star, burning hotter than our own Sun in the constellation Eridanus, one of the few thousand stars bright enough to carry an officially recognised name. On a dark, clear night you can find it with your own eyes.
Most stars in the sky are anonymous points of light. Acamar 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.
