Secunda Hyadum: the yellow star of Taurus
yellow · Taurus · δ1 Tau
Secunda Hyadum is a yellow star in the constellation Taurus, 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. Secunda Hyadum 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.
