The axis of Earth wobbles (this is called "precession"), and is therefore not always lined up with the same star. Polaris lies roughly one half degree from the NCP, so this particular star appears to remain stationary hour after hour and night after night. Unfortunately, latitude alone is insufficient to pinpoint a location on the surface of the earth. It will align most closely with the north celestial pole – the point in the sky directly above Earth’s north rotational axis – on March 24, 2100.
