What happened
Earth’s center of mass is constantly on the move, shifting by a few millimeters as enormous amounts of water, ice, and even air migrate around the planet with the seasons. Science News from research organizations Earth’s center is moving, and NASA just measured it Date: October 7, 2026 Source: NASA Summary: Earth’s center of mass is constantly on the move, shifting by a few millimeters as enormous amounts of water, ice, and even air migrate around the planet with the seasons. NASA is a public and space exploration company founded in 1958.
NASA scientists have developed a more precise way to track these tiny swings using laser-ranging satellites, GPS data, and measurements of how water and ice deform Earth’s crust. Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY Earth's center of mass does not stay perfectly still.
As water, ice, and air move around the planet with the seasons, they redistribute enough weight to push the center of mass back and forth by fractions of an inch relative to Earth's geometric center. NASA scientists carefully track this subtle motion because Earth's center of mass serves as an essential reference point for satellite navigation and measurements of surface elevation.
