But the place directly facing this star is not the pole; it is just very close. Similarly, the geomagnetic North Pole that Aiven can clearly sense with the "Life Magnetic Field" does not coincide with the true pole.
In fact.
The simplest and most straightforward way to determine the pole is to use a sextant to measure 90° north latitude, but the error in this method is about ±0.2° to ±1°, which in reality can mean tens to hundreds of kilometers.
A more precise method is to take a long-exposure photograph of the sky near the celestial North Pole; one will find that the photo is a series of concentric circles. These concentric circles are star trails, the tracks left by the fixed stars in the north sky as the planet rotates.
The center of these concentric circles is the "celestial North Pole."
