Errai

Its story

Errai is a bright neighbour just 46 light-years away, an orange K-type giant in the constellation of Cepheus. Owing to Earth's slow axial wobble, in some two thousand years it will take over from Polaris as the pole star of the northern hemisphere: future stellar compasses will seek it instead. Its Arabic name, «Ar-Rā‘ī», means «the shepherd», and it keeps watch from the circumpolar sky while around it a small retinue of stars sketches the crowned head of the Ethiopian king.
