Its story

Mu Cassiopeiae is a rarity: a yellow star just 24.6 light-years away, a near neighbour of the Sun and one of the few at that distance visible to the unaided eye. It belongs to the galaxy's ancient population, poor in heavy metals, and its proper motion is among the highest of the northern sky —it crosses the vault at a noticeable pace over centuries.
