Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth’s center of mass is a crucial reference point for satellite navigation and elevation measurements. A team, led […] Source: https://www.nasa.gov/science-research/earth-science/nasa-watches-earths-weight-finds-center-of-mass/
