However, the longitude lines on a globe lead to the true poles, because the three-dimensional representation avoids those limitations.
Within a margin of error of 1°, the true north direction can be approximated by the position of the pole star Polaris which would currently appear to be very close to the intersection, tracing a tiny circle in the sky each sidereal day.
Due to the axial precession of Earth, true north rotates in an arc with respect to the stars that takes approximately 25,000 years to complete.
Around 2101–2103, Polaris will make its closest approach to the celestial north pole (extrapolated from recent Earth precession).
