Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...

When you picture the Earth spinning in space you imagine it rotating just like a globe does, with two static poles and a line running from north to south. Unfortunately, things aren't nearly that ...

Since its formation, the Earth has been revolving west to east on its axis. If one day our planet started rotating in the ...

Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track ...

Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say the planet’s axis has shifted by more than 30 inches, a subtle but measurable ...

The Earth's spin isn't as consistent as it may seem. In fact, it naturally drifts and wobbles on its axis over time, and that's generally chalked up to the way mass is distributed and redistributed ...

The Earth, moving in its orbit around the Sun and spinning on its axis, appears to make a closed, unchanging, elliptical orbit. If we look to a high-enough precision, however, we'll find that our ...
