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 ...

Using a complex model to perform a theoretical calculation based on a U.S. Geological Survey, Richard Gross of NASA's Jet Propulsion Laboratory (JPL) has determined that by changing the distribution ...
