Polaris is used as a celestial reference point for Earth's latitude system because it is located almost directly above the North Pole. This means that it remains relatively fixed in the sky as the Earth rotates, making it a reliable reference point for determining one's latitude in the Northern Hemisphere.
The constellation is the the Big Dipper (USA) or the Plough (UK).
the axis is a imaginary line that cuts trough the earth it points southwest and northeast
The local zenith is perpendicular to the rotation axis of the Earth at a specific location. It represents the point directly above an observer, pointing towards the celestial sphere. The rotation axis of the Earth is an imaginary line around which the Earth spins.
Constellations near Polaris, known as circumpolar constellations, never dip below the horizon as seen from the northern hemisphere. This is because Polaris is located very close to the North Celestial Pole, around which the sky appears to rotate. As a result, these constellations remain visible in the night sky throughout the year, constantly circling around Polaris.

The poles of Earth are fixed due to the planet's axial tilt and rotation. The North Pole points towards the North Star, Polaris, creating a stable reference point. This axial alignment allows Earth to maintain its axis orientation despite movements in its orbit.
The axis is always aimed toward a point in the sky near Polaris :))

It is the last star at the tip of the handle of the Little Dipper. The Big Dipper's first two bowl stars (often called the pointer stars) point towards Polaris, but Polaris is not in the Big Dipper.
Polaris is used as a celestial reference point for Earth's latitude system because it is located almost directly above the North Pole. This means that it remains relatively fixed in the sky as the Earth rotates, making it a reliable reference point for determining one's latitude in the Northern Hemisphere.
Currently, the north end of the Earth's rotation axis points toward a point in the skythat happens to be only about 1/3 of a degree from a relatively bright star. The resultis that the star seems to never move, and is called "The North Star".
The pointer stars in the Big Dipper point towards the North Star, also known as Polaris. Polaris is located directly above the North Pole and remains nearly stationary in the sky. This makes it a useful navigational tool for finding north.
The constellation is the the Big Dipper (USA) or the Plough (UK).
The point would be in darkness for the complete rotation of the planet
Earth is round and so doesn't "point" anywhere. Its axis of rotation currently points in the general direction of Polaris on one end and ... not really much of anywhere on the other end.
Currently the Earth's pole points toward Polaris in Ursa Minor. 5000 years ago it pointed towards Vega.
