Key Takeaways on the Speed of Earth's Rotation The speed of Earth's rotation is about 1,000 miles per hour relative to its axis. Your exact speed of rotation due to Earth's spin depends on your ...

University of Reading’s Dr James O’Donoghue explains why no day is ever really the same – horologically speaking.

Since 2020, Earth has continued breaking its speed records. The shortest day ever recorded was on July 5, 2024, when Earth’s rotation was completed 1.66 milliseconds faster than usual.

To find out how fast the Earth is spinning at all, you need to find a reference frame in which, ideally, nothing is moving.

A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why.

Zotov predicts Earth’s rotation may soon decelerate once again. If he’s right, this sudden speeding-up could prove to be just ...

The mass shift of this melting ice is not only causing changes in Earth’s rotation speed, but also in its rotation axis, according to research led by Benedikt Soja, an assistant professor at the ...

Will the earth experience "colder weather than ever before" during the "aphelion phenomenon" in August, 2025, as its ...

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they ...

Earth completes one full rotation on its axis in 24 hours, or about 86,400 seconds, plus or minus a millisecond or so, according to Timeanddate.com. Before 2020, Earth's shortest length of day was ...

Many of us have heard the term “blue moon,” which refers to two full moons during a single month. Thanks to astronomy enthusiasts and journalists, when there are two new moons during the same month, ...
