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. Earth's rotational axis is an imaginary straight line that runs through the North … See more The impact around 4.5 billion years ago is described in the Giant Impact Hypothesis, which is the current prevailing theory on how the Moon was formed and how Earth got its tilt. Ever since this impact, Earth has been orbiting the … See more Axial precession can be described as a slow gyration of Earth's axis about another line intersecting it.

NASA Study Solves Two Mysteries About Wobbling Earth
WebSep 19, 2024 · Earth is not a perfect sphere. When it rotates on its spin axis -- an imaginary line that passes through the North and South Poles -- it drifts and wobbles. These spin-axis movements are scientifically referred to as "polar motion." Measurements for the 20 th century show that the spin axis drifted about 4 inches (10 centimeters) per year. Over ... WebMay 10, 2024 · Earth’s wobble causes variations in the seasons, creating cooler or warmer summers depending on what hemisphere is at perihelion, with warmer summers for the hemisphere tilted toward the Sun. … WebBy itself, the wobble of Earth's axis does not directly cause temperature changes like orbital shape and tilt. But it changes the portion of the orbit at which a given season occurs - that is, it changes when a particular season will occur.
