Alderamin

Cepheus the king passes high overhead tonight. The constellation’s five main stars form a pentagon. None of them is especially bright, though, so you’ll probably need a star chart to find his majesty.
Even so, the brightest star in Cepheus has quite a future: It’s destined to become the North Star.
Right now the North Star is Polaris, the star at the end of the handle of the Little Dipper. The star marks true north because Earth’s axis happens to point nearly straight at it. So as Earth spins, Polaris remains in the same position, never rising or setting.
However, as the gravitational forces of the Sun and Moon tug at our planet, it wobbles. That makes its rotation axis gradually point elsewhere. In the year 7500 A.D., it’ll point at the brightest star in Cepheus, Alderamin.
Alderamin won’t be as good a North Star as Polaris is now. For one thing, it isn’t quite as bright. For another, while Polaris is less than a degree from the celestial pole, Alderamin won’t get closer than a couple
