Earth's axial precession, a slow wobble of its rotational axis, is analogous to the gyroscopic motion of a spinning top. The primary cause of Earth's precession is the gravitational influence of the ...

Exoplanet Kepler 413-b orbits a close pair of orange and red dwarf stars once every 66 days. Not only does the planet's axis wobble like crazy, its orbit about the stars wobbles too. Credit: NASA, ESA ...

Scientists in Germany have used a highly sensitive underground ring laser to track Earth's axial wobble without relying on telescopes, satellites, or external reference signals. The researchers from ...

As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in ...

An in-depth study conducted by NASA found that humans are responsible for the increasing wobble detected as Earth spins on its axis. When you think of Earth you may think of an exact sphere, but Earth ...

Earth's axis — the invisible line around which it spins — is bookended by the north and south poles. The axis tilts, and thus the pole shift, depending on how weight is distributed across Earth's ...

When the Earth rotates, it doesn’t just spin. The Earth also wobbles on its axis like a top, and now a NASA study has clarified just what causes that wobble. The study identifies three separate causes ...

Humans are responsible for some of the wobble in Earth's spin. Since 1899, the Earth's axis of spin has shifted about 34 feet (10.5 meters). Now, research quantifies the reasons why and finds that a ...
