Here's why:
* Polaris is aligned with the Earth's axis of rotation: This means it sits directly above the North Pole.
* Earth's rotation: As the Earth spins on its axis, Polaris appears stationary in the sky, while other stars seem to circle around it.
* Latitude: The higher your latitude in the Northern Hemisphere, the higher Polaris appears in the sky. At the North Pole, Polaris is directly overhead.
Therefore, as long as you are in the Northern Hemisphere, you'll always be able to see Polaris.
It's possible that you're thinking about a different star, or maybe a situation where the horizon is obscured by something like a tall building or mountain, making it seem like the North Star has sunk below the horizon.
