How was polaris discovered?

Polaris, also known as the North Star, has been recognized since ancient times due to its position nearly aligned with the Earth's rotational axis. Its identification as a significant navigational star dates back to ancient Greek astronomers, who noted its brightness and fixed position in the night sky. The star's importance grew over centuries, particularly for navigation, as it remains relatively stationary, making it a reliable point for travelers in the Northern Hemisphere. Its designation as the North Star became formalized in later astronomical studies, solidifying its role in celestial navigation.
