Each of the two points on the surface of a celestial body or planet placed on the axis of rotation is called a geographic pole. Although geographic poles are usually at least approximately identifiable as the two points furthest from the orbital plane, this is not a general rule: a famous example is Uranus, whose axis of rotation forms an angle of only 8 degrees with the orbital plane. As far as the Earth is concerned, what are usually called the North Pole and the South Pole are precisely the geographic poles, which are accepted by all as an absolute reference in cartography. Geographical poles should not be confused with magnetic poles, which can also exist on a planet, and which in general do not coincide with geographic ones. On Earth, this means that when you orient yourself with a magnetic compass, you have to take into account the magnetic declination.
