Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. [6] It is denoted by the Greek letter Epsilon ε. Earth currently has an axial tilt of about 23.44°. [7]
The angle of the Earth's axial tilt with respect to the orbital plane (the obliquity of the ecliptic) varies between 22.1° and 24.5°, over a cycle of about 41,000 years. The current tilt is 23.44°, roughly halfway between its extreme values.
The tilt of fictitious Earth's axis and the eccentricity of its orbit are exaggerated. ... has increased from the current 60.3 to approximately 66.5 Earth radii ...
Seasons are the result from the Earth's axis of rotation being tilted with respect to its orbital plane. ... The Earth's tilt is the reason for the seasons, stated NASA. So spring, summer, winter ...
The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the Earth’s tilt of roughly 31.5 inches. The ...

Like a gyroscope, the overall effect is a slight "wobble" in the movement of the axis of a planet. Currently the tilt of the Earth's axis to its orbital plane (obliquity of the ecliptic) is 23.44 degrees, but this angle changes slowly (over thousands of years).
In less than two decades, Earth has tilted 31.5 inches. That shouldn't happen. So why did it?
