Delta Crucis
Delta Crucis: the blue star of Crux
blue · Crux · δ Cru
Delta Crucis is a blue star in the constellation Crux, 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. Delta Crucis 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.
