A: Astronomers call the wobble of Earth’s axis precession. While most of us are familiar with our planet’s primary motions — rotation (spinning once a day) and revolution (orbiting the Sun once a year ...

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 ...

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 ...

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 ...

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. Now, research quantifies the reasons why and finds that a third is due to ...

Millimeter deviations from the expected wobble of the Earth's axis are giving geophysicists clues to what happens 1,800 miles underground, at the boundary between the Earth's mantle and its iron core.

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 ...

That day, a Wednesday, was 1.59 milliseconds shorter than ever before. It happened because the Earth isn't perfectly spherical and can "wobble" on its axis. The Earth had its shortest ever day this ...
