Paleoclimate and archaeological evidence tells us that, 11,000-5,000 years ago, the Earth's slow orbital 'wobble' transformed today's Sahara desert to a land covered with vegetation and lakes.

First of all the rotation axis changes relative to the Earth’s surface which is referred to as polar motion. The main component of polar motion is the so-called Chandler wobble. Although it was ...

Located less than 20 light years away, HD 20794d could potentially be one of the most Earth-like planets found so far, ...

It reveals that the Earth's inner structure is less synchronized than we previously believed. The inner, solid part of Earth's core behaves like a spinning top; it rotates around its axis along ...

and near-Earth asteroids that approach Earth's orbital distance to within about 28 million miles and may pose an impact danger," NASA states on its website. Asteroids are known to range in size ...

Space situational awareness remains limited; debris smaller than a tennis ball often goes undetected, yet even a tiny object could cause catastrophic damage due to high orbital speeds. Low Earth ...

Star systems that don't have an orbital plane oriented edge-on toward Earth lend themselves to a tactic called the "wobble" method, also known as the radial velocity method. The mass of an ...

That world was detected around the sunlike star 51 Pegasi, a mere 50 light-years from Earth. The rate of exoplanet ... also called the Doppler wobble, with more than 400 newfound planets to ...
