Achird: the golden star of Cassiopeia

golden · Cassiopeia · η Cas

Achird is a golden star, warmer-toned than our Sun in the constellation Cassiopeia, 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. Achird 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.
