Because of Earth’s dynamic climate, winds and atmospheric pressure systems experience constant change. These fluctuations may affect how our planet rotates on its axis, according to NASA-funded ...

Researchers believe that in the Jurassic Period, it took Earth just 23 hours to make a complete rotation around its axis. Scientists have found that the length of a day on Earth is increasing each ...

“This means that mass is moved from the ground to above the ground—further away from the Earth's spin axis.” In all of these cases too, however, the effect is to slow the Earth, not speed it up.

Planetary Tailspin The Earth's rotation is about to accelerate significantly. According to scientists, July 9, July 22, and August 5 of this year will be some of the shortest days in years as a ...

Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are causing feedback beneath the surface, impacting the planet's molten core.

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...

Is Earth's rotation speeding up? Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds.

Earth as seen by NOAA’s GOES-18 weather satellite. NOAA Satellites A day is a period in which Earth makes a complete rotation around its axis.

Instead Earth’s so-called “True North Pole” is whichever place that is northernmost on the planet, a fact determined by where the globe’s axis of rotation meets its surface.

Earth's rotation on its axis determines our daily cycle of sunrise and sunset. Each rotation takes 24 hours, or 86,400 seconds.

“This means that mass is moved from the ground to above the ground—further away from the Earth's spin axis.” In all of these cases too, however, the effect is to slow the Earth, not speed it up.
