And interestingly, by 4,000 CE, the slow wobble of Earth’s axis will have moved Gamma Cephei into position as our North Star.
How to find Gamma CepheiFor much of the Northern Hemisphere, orange-yellow Gamma Cephei shines as a circumpolar star.
Circumpolar stars closely circle the North Star (or Pole Star), neither rising nor setting because they’re always above the horizon.
A future North StarThe Earth’s north rotation axis points to the north celestial pole, and this is very close to Polaris, our present North Star.
Bottom line: Gamma Cephei – or Errai – is a binary star system that will one day be Earth’s North Star.
