Precession

This phenomena of Earth's movement takes a 26,000 year cycle.

Step-by-step explanation:

Precession is a phenomenon in which the Earth's axis of rotation moves slowly making a conical shape. This phenomena takes 26,000 years. The main reason behind this phenomena is the gravitational pull by the sun and the moon. This causes the Earth to change the shape from a sphere to a slight flattened one.
