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: WebSep 19, 2024 · Scientists ID three causes of Earth's spin axis drift. The observed direction of polar motion, shown as a light blue line, compared with the sum (pink line) of the influence of Greenland ice loss (blue), postglacial rebound (yellow) and deep mantle convection (red). The contribution of mantle convection is highly uncertain. canature health technology group co. ltd

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".
