There's a giant dam in China which is slowing down the Earth's rotation and satellite images of the Three Gorges had some ...

We still don’t fully understand what determines the rotation rate of giant planets; this is a key open topic in planetary science. Let’s take a look at the differences between the giant ...

THE recent radar measurements of Mercury indicate that the period of rotation of the planet is 59 ± 5 days 1. This result is in complete disagreement with the previously quoted value of 88 days ...

If precise enough, the measurements of the rotation with all of the wobbles place constraints on the structure and composition of the very deep parts of the planet, Dr. Le Maistre said.

However, there is a slightly more complicated theory: the planet's fast-moving atmosphere interacting with its surface altered its speed and rotation. "We think of the atmosphere as a thin ...

Like the majority of the solar system's planets, this rotation is counter-clockwise, but as well as being significantly slower than Earth's rotation, the sun's rotation is much more complex.

And a new study from scientists in China says the core has actually slowed its rotation. It's just the latest attempt to describe what's going on at the very center of the planet, a part of the ...
