Earth's axial tilt actually oscillates between 22.1 and 24.5 degrees. The reason for this changing obliquity angle is that Earth's axis also wobbles around itself. This wobble motion is called axial precession, also known as precession of the equinoxes. It is caused by the gravitational force from the Sun, the Moon, and … See more In astronomy, an axisrefers to the imaginary line that an object, usually a planet, rotates around.
