Earth's axis is the imaginary line which goes through the north and south poles and around which Earth spins. It is inclined 66.5 degrees from Earth's orbital plane, which means that it is tilted 23.5 degrees from a vertical 90 degrees.

Generally, an axis is any imaginary or physical line that prescribes an object's movement. A taut string that goes through the center of a spinning ball would be an example of a physical axis. The string, as the axis, would represent the part of the ball that is not really moving or that is moving the least.

An axis also includes the point that is known as the center of gravity.
The Earth's axis is an imaginary line or shaft that the Earth looks to be turning around, like a meatball on a skewer. It runs more or less through the poles.
