Alpheratz: the blue-white star of Andromeda

blue-white · Andromeda · α And

Alpheratz is a blue-white star — the colour of the hottest, youngest suns in the constellation Andromeda, 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. Alpheratz 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.
