Understand that the North Star can be used to determine geographic north.
Most stars change their positions as Earth rotates and revolves.
The axis of Earth is inclined with respect to the poles and remains constant. The North Star can be used to determine geographic north. The numbers specifying location on Earth are known as latitude and longitude. The angle at which the North Star can be observed relative to the horizon differs in each part of the world. At the equator, the angle is O degrees.
