There are so many stars ... wherever the north end of the earth's axis happened
to point during our Century, there's a good chance there would be a star near that
point in the sky.
But it's not a sure thing. In the Southern Hemisphere, there's no bright star near the
South Celestial Pole ... nothing like a "South Star" to correspond to our "North Star.
There is no particular reason. It just so happens that Earth's north pole coincidentally points in the direction of the star Polaris.
It does, but over millions of years, the earth tilts a little and there is a new north star.
The North Star sits at a point in the sky near where the northern axis of the earth sits. This means that the North star's relative position in the sky does not change. In fact, in a 24 hour Earth cycle, the north star only moves in a small circle.
Because the earth's north pole happens to point [very close] to Polaris.
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".
Yes. The north star is an actual star that is roughly aligned with Earth's north pole.
The altitude of the North Star will not change from any point on Earth. However, the declination changes depending upon where you are and when - It is less than 90 degrees.
The farthest point north on the Earth is the North Pole. The farthest point south on the Earth is the South Pole.
The northernmot point on the earth is the North Pole. It may not be on land, but it is "on the earth."

True north runs from any point on the Earth's surface to the North Pole.
The two pointer stars point to Polaris, the north star
The Northern Star is a constantly fixed point in space marked by a star to help aid in navigation by early sailors to stay on course during the night. The North Star is the star which lies closest to a point in the sky above the northern polar axis of the Earth. This star is called Polaris or the Pole Star
