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.
