<> Hey your answer mate <>

Pole star :-

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.

Where is it found :-

• The North Star or Pole Star – aka Polaris – is famous for holding nearly still in our sky while the entire northern sky moves around it.

• That's because it's located nearly at the north celestial pole, the point around which the entire northern sky turns. Polaris marks the way due north.

Types :-

Currently, Earth's pole stars are Polaris (Alpha Ursae Minoris), a magnitude-2 star aligned approximately with its northern axis, and a pre-eminent star in celestial navigation, and Polaris Australis (Sigma Octantis), a much dimmer star.
