The term "Polestar" typically refers to Polaris, the current North Star. Polaris is a star located about 434 light-years away from Earth.

Stars are not part of our solar system. Our solar system consists of the Sun, planets, moons, asteroids, and comets that orbit the Sun due to its gravitational pull.

Therefore, Polaris (the Polestar) is not a member of our solar system.
