Earth rotation and polar motion prediction encompass the estimation and forecasting of key parameters that describe the rotational behaviour of our planet. These predictions are pivotal for ...

Nearby planets can affect how one planet 'wobbles' on its spin axis, which contributes to seasons. Mark Garlick/Science Photo Library via Getty Images Spring, summer, fall and winter – the seasons on ...

Earth’s rotation dynamics are influenced by a range of internal and external factors, with Free Core Nutation (FCN) standing out as a key phenomenon. FCN arises from the slight misalignment between ...

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar ...

A recent groundbreaking study published in Geophysical Research Letters has revealed an astonishing new insight: Earth’s rotational axis has shifted 31.5 inches in less than two decades, largely due ...

Astronomers from the University of Helsinki have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into ...

The Earth in orbit around the Sun, with its rotational axis shown. Earth's axial tilt does not change appreciably in direction or magnitude over the course of a day or even a year, which is why the ...
