23.5 degrees
The tilt of the earth's axis is called ecliptic. The tilt of the earth's axis will vary in most cases between 22.1 and 24.5 degrees.
the earth spins on an imaginary line called axis.
This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane.

its 66.5 degrees
Earth's rotational axis has an inclination of 23.5 degrees. The angle is measured from a line that is perpendicular to Earth's plane of rotation (the Ecliptic).
It is explained by our choice of reference directions. If we decided to compare the direction of the Earth's axis to something different, then the number would change.
The tilt of the Earth's axis in relation to the plane of its orbit.
The inclination of Earth's axis does not change over the course of a year; it remains constant at about 23.5 degrees. This tilt is what causes the seasons as the Earth orbits the Sun.
