  2. Earth's rotation - Wikipedia

    en.wikipedia.org/wiki/Earth's_rotation

    Earth's rotation imaged by Deep Space Climate Observatory, showing tilt. Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, Earth turns counterclockwise.

  3. Inner core super-rotation - Wikipedia

    en.wikipedia.org/wiki/Inner_core_super-rotation

    Waves were observed to travel faster between north and south than along the equatorial plane. A model for the inner core with uniform anisotropy had a direction of fastest travel tilted at an angle 10° from the spin axis of the Earth. [15] Since then, the model for the anisotropy has become more complex. The top 100 kilometers are isotropic.

  4. Atmospheric super-rotation - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_super-rotation

    Atmospheric super-rotation is a phenomenon where a planet's atmosphere rotates faster than the planet itself. This behavior is observed in the atmospheres of Venus, Titan, Jupiter, and Saturn. Venus exhibits the most extreme super-rotation, with its atmosphere circling the planet in four Earth days, much faster than the planet's own rotation of ...

  5. Earth Has Tilted 31.5 Inches. That Shouldn't Happen. - AOL

    But now—thanks to a study published in the journal Geophysical Research Letters—we can see that, in less than two decades, Earth has tilted 31.5 inches as a result of pumping groundwater. This ...

  6. Earth’s spin is believed to be speeding up - AOL

    Earth has reportedly reached its quickest spin speeds in the past half-century.

  7. Earth’s core might be reversing its spin. It ‘won’t affect ...

    Just as the Earth spins, the planet’s inner core turns, though not necessarily at the same speed, and some research indicates the core moves faster, according to the National Science Foundation.

  8. Retrograde and prograde motion - Wikipedia

    en.wikipedia.org/wiki/Retrograde_and_prograde_motion

    Meteoroids in a retrograde orbit around the Sun hit the Earth with a faster relative speed than prograde meteoroids and tend to burn up in the atmosphere and are more likely to hit the side of the Earth facing away from the Sun (i.e. at night) whereas the prograde meteoroids have slower closing speeds and more often land as meteorites and tend ...

  9. Equatorial bulge - Wikipedia

    en.wikipedia.org/wiki/Equatorial_bulge

    The Earth's rotation rate is still slowing down, though gradually, by about two thousandths of a second per rotation every 100 years. [1] Estimates of how fast the Earth was rotating in the past vary, because it is not known exactly how the moon was formed. Estimates of the Earth's rotation 500 million years ago are around 20 modern hours per ...
