Earth’s Center of Mass Is Moving — And Satellites Can Now Track It

Scientists have discovered that Earth’s center of mass is constantly shifting as water, snow, ice, and air move around the planet.Using satellites, GPS data, and improved models, researchers found these seasonal movements are smaller than previously thought—but still large enough to matter for GPS, global mapping, and precision navigation. The findings reveal just how much Earth's surface is constantly reshaping its position in space.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
