The star that is directly in line with the axis of the Earth is Polaris, also known as the North Star. Polaris is located nearly at the celestial north pole, making it a pivotal point for navigation in the Northern Hemisphere. Its position remains relatively fixed in the night sky, helping travelers and navigators orient themselves.

What stars does not move in the night sky because it is directly over the Earth's axis of rotation?
Which following stars . . you didn't give any names :) But the Pole star is almost in line with the Earth's north and south poles, less than 1 degree off.
What is the projections of Earth's rotational axis on the sky?
The projection of Earth's rotational axis on the sky forms a line around which the stars appear to rotate. This line is called the celestial equator and divides the sky into northern and southern hemispheres. The celestial poles are located where this line intersects the sky, with the North Celestial Pole aligned closely with the star Polaris.
Why do constellations appear to revolve around the Pole star?
This is because the Pole Star (i.e. Polaris, in the Northern hemisphere) is within a degree of the Earth's centre of rotation. That is, the north pole is in line with this particular star. Thus, as the Earth rotates, Polaris does not appear to move in the sky, and the rest of the stars appear to revolve around it.
What star did the compass needle point when it was pointing north?
When a compass needle points north, it is generally aligning itself with the Earth's magnetic field rather than directly pointing to a specific star. However, in the Northern Hemisphere, the North Star, or Polaris, is located nearly in line with the Earth's rotational axis and is often used as a reference for true north. Polaris is not exactly magnetic north, but it serves as a useful guide for navigation. In the Southern Hemisphere, the Southern Cross constellation is often used to find the south celestial pole, but it does not correlate directly with magnetic north either.
If pole star doesnt move then how can you see pole star during revolution of earth?
The Pole Star appears stationary in the night sky because it lies almost directly above the Earth's North Pole. As the Earth rotates on its axis, the North Pole always points in the same direction towards the Pole Star. This makes the Pole Star visible every night, regardless of the Earth's revolution around the Sun.
What is a polaries star?
Polaris is a star which is directly above the North Pole and therefore appears to be stationary as the Earth rotates on its axis.
What is the name of the fixed star that line up with the north pole of earth's axis?
It is called Zenith.
What does the earths axis always point towards?
the axis is a imaginary line that cuts trough the earth it points southwest and northeast

Does constellation Orion rotate about the pole star?
All the constellations appear to rotate round the pole star because the pole star is in line with the axis that the Earth rotates around with us on board.
Towards which star does the earth's axis appear to be tilted?
The north star
How can one use a compass to find the North Star?
To find the North Star using a compass, first locate the North direction on the compass. Then, hold the compass level and point the direction of the North arrow towards the North Star. The North Star is located directly in line with the Earth's axis, so following the compass's North direction should lead you to it.
Why does the pole star appers stationary?
As the earth revolves in its orbit around the sun, it acts like a gigantic gyroscope. The tilt in the pole is always oriented (with some complex variations that can't be covered here) toward the pole star. The star is so far away that the width of earth's orbit doesn't have a great effect on the star's position in our sky. The pole star does appear to move a little. It is very close to the celestial position of the north pole, but it is not exactly on the point.
Is the earth's atmosphere heated directly by a planet or a star?
Earth is heated by the sun, which is a star.
Why do constellations appear to revolve around the Pole star?

What is the nothern star?
The Northern Star is also known as Polaris. This is the star that the Earth's axis of rotation approximately points to.
