Explanation:

A pole star or polar star is a star, preferably bright, nearly aligned with the axis of a rotating astronomical body. Currently, Earth's pole stars are Polaris, a magnitude-2 star aligned approximately with its northern axis, and a pre-eminent star in celestial navigation, and Polaris Australis, a much dimmer star. From around 1700 BC until just after 300 AD, Kochab and Pherkad were twin northern pole stars, though neither was as close to the pole as Polaris is now.
