Polaris
Polaris is a fixed star located in the constellation Ursa Minor, also known as the North Star. It is the brightest star in the constellation and has been used for centuries as a navigational tool for mariners in the Northern Hemisphere. Polaris is located almost directly above the Earth's North Pole, making it a reliable point of reference for determining true north. By measuring the angle between the horizon and Polaris with a sextant, sailors can determine their latitude and plot their course. Polaris has played a crucial role in maritime navigation throughout history and continues to be an important tool for modern sailors.
