Rarely does anyone other than astronomers ever think about precession since a full cycle takes 25,800 years to complete. For most of modern history, the northern pole of our Earth’s axis has ...

Axial precession also occurs with binary stars. Measuring this effect is very difficult, however, because it's often hard to measure the rotational orientation of a distant star.

This is known as axial precession or just axial wobble. And our axis completes a full circle about every 23,000 years.

With axial precession being a scientific fact, why doesn’t tropical astrology factor it into its system? Well, in all honesty, precession makes things complicated.

Axial precession occurs on a cycle of roughly 26,000 years and arises because Earth wobbles slightly as it rotates, similar to the wobble of a toy top.

New research suggests that Earth’s orbital variations—the slow changes in its tilt, axial precession, and shape of its orbit—may influence the timing of massive volcanic eruptions, reshaping ...

For example, the changes in axial tilt require 41,000 years to go through a complete cycle. The different cycles overlap, reinforcing or suppressing each other's effects and creating a complex set ...

The wobble, known as axial precession, causes an upwell of nitrogen-poor (but phosphorus-rich) water from the deep ocean roughly every 23,000 years. Blue-green algae such as Trichodesmium (above) feed ...
