Rasalhague

Rasalhague: the white star of Ophiuchus

white · Ophiuchus · α Oph

Rasalhague is a white star, burning hotter than our own Sun in the constellation Ophiuchus, 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. Rasalhague 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.
