Does the angel of earths axis change during its orbit?

Yes, the angle of Earth's axis, known as axial tilt or obliquity, does change slightly over long periods due to gravitational forces from the Sun and the Moon, as well as other celestial bodies. This tilt varies between approximately 22.1 and 24.5 degrees over a cycle of about 41,000 years. However, this change is gradual and does not significantly affect Earth's orbit itself, which remains stable in the short term.
