North Star
North Star, also known as Polaris, is a bright star located almost directly above the Earth's North Pole. It is a reliable navigational tool for mariners in the Northern Hemisphere, as it remains almost stationary in the sky while other stars appear to rotate around it. By determining the angle between the horizon and the North Star using a sextant, sailors can calculate their latitude and determine their position on the globe. The North Star has been used for navigation for centuries and is an important reference point for celestial navigation.
