Haedus
Haedus: the blue-white star of Auriga
blue-white · Auriga · η Aur
Haedus is a blue-white star — the colour of the hottest, youngest suns in the constellation Auriga, 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. Haedus 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.
