Junnanmen: the blue-white star of Andromeda
blue-white · Andromeda · φ And
Junnanmen 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. It rewards a pair of binoculars on a clear night.
Most stars in the sky are anonymous points of light. Junnanmen 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.
