The instructions for finding directions using reference stars will gradually become dated due to the precession of Earth’s axes, which changes the direction in which the planet’s north and south poles point. This will cause different stars to move closer to the Celestial North and South Poles. Polaris will only be the North Star for another thousand years, as the Celestial North Pole moves in the direction of the constellation Cepheus. Then the title of North Star will be taken over by Gamma Cepheus (Errai). It will be about 1.8 degrees from true north at its closest, and not nearly as bright as Polaris, but it'll be the best that we will have.The instructions for finding your direction by following a star’s position over time will still work as long as Earth continues to rotate west to east.
