WebIn this simulation, we show the average speed of Earth’s spin axis—called polar motion—driven by several geophysical sources during two time periods: 1900-2000 and 2003-2015. Data rendered here are results from two papers published by ISSM team at NASA’s JPL, Caltech: WebThis is an activity about how the Earth's axial tilt causes its seasons. Learners will make a model using polystyrene spheres and a light bulb to represent the Earth-Sun system, showing why the tilt of the Earth’s spin axis causes its seasons due to …

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. A complete wobble of Earth's axis takes around 26,000 years. It outlines the shape of a pair of cones or two spinning tops … See more Today, on February 22, 2024 at noon, Earth's axial tilt, or mean obliquity was 23.43627° or 23°26'10.5". Earth's mean obliquity today is about 0.00001°, or 0.04", less than 30 days ago.
