Answer:
Just above the axis of the Earth
Step-by-step explanation:
The pole star is the star that lies just above the axis of the Earth. Contrary to the belief that it is exactly above the axis of Earth it is actually a little bit shifted. But that separation is very small i.e. 0.5°. Also, pole star is just a designation. For northern hemisphere, Polaris is the pole star.
In the diagram, Polaris will be the star just above the axis of Earth.
Just because it lies above the axis of the Earth it doesn't appear to move from its place.
