Polaris, known as the North Star, sits more or less directly above Earth’s north pole along our planet’s rotational axis. This is the imaginary line that extends through the planet and out of the north and south poles. Earth rotates around this line, like a spinning top.
Where is the North Star located right now?
Polaris is located in the constellation known as Ursa Minor, the Little Bear, which includes the group of stars called the Little Dipper. Polaris, the North Star, lies at the end of the handle of the Little Dipper.
Is North Star always north?
