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 ...

Earth wobbles on its axis like a spinning top, a motion called precession. This wobble takes about 26,000 years to complete one full circle. Different stars have served as the North Star throughout ...

Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...

The precession of the equinoxes refers to the precession of Earth's axis of rotation with respect to inertial space. The precession of the equinoxes is caused by the differential gravitational forces ...

Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...

As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in ...

During the process of accumulation, planets acquire rotational angular momentum from the relative motions at collision of the material from which they accrete 3,4,5,6,7. Owing to the symmetry of the ...

All shook up A strange planet with erratic, rapidly changing seasons has been discovered orbiting two stars, by scientists using NASA's planet hunting Kepler space telescope. The planet's strange ...

Ancient Chinese astronomer Shi Shen’s star catalog, known as The Star Manual of Master Shi, is now considered the oldest star chart in the world. Later observations written into the catalog showed ...
