The Earth's axis is tilted at an angle of 23.5 degrees with respect to a line perpendicular to the plane of the ecliptic, which is the plane of the Earth's orbit around the Sun. This tilt gives rise to the seasons as the Earth orbits around the Sun. The angle does not vary through the year, it remains fixed.
