The altitude of Polaris, or its angle above the horizon, corresponds to your latitude in the Northern Hemisphere. For example, if Polaris is observed at an altitude of 30 degrees, you are located at approximately 30 degrees north latitude. This relationship allows navigators and astronomers to determine their geographic position using the stars. However, it is important to note that this method is applicable only in the Northern Hemisphere, as Polaris is not visible from the Southern Hemisphere.
