Navigational stars are celestial bodies used by sailors and travelers to determine their position and direction at sea or in the wilderness. These stars are typically bright and easily identifiable, making them reliable reference points. The most famous navigational star is Polaris, also known as the North Star, which is located nearly directly above the North Pole. Historically, navigational stars have played a crucial role in exploration and trade. By observing the position of these stars, navigators could calculate their latitude and, in some cases, their longitude. This practice has been essential for maritime navigation for centuries, guiding explorers like Christopher Columbus and Ferdinand Magellan on their journeys.
