Earth precession

WebMay 10, 2024 · Figure 3: Two variations of precession cycles. Left: precession of Earth’s rotational axis. Right: precession of Earth’s orbit. Earth’s wobble causes variations in the seasons, creating cooler or warmer summers depending on what hemisphere is at perihelion, with warmer summers for the hemisphere tilted toward the Sun. Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, … See more Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, but the angular velocity vector changes orientation with time.

In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In the absence of precession, the astronomical body's orbit would show axial parallelism. In particular, axial precession can refer to the gradual shift in the orientation of Earth's axis of rotation in a cycle of approximately 26,000 years. This is similar to the precession of a spinning top, with the axis tracing out a pair of cones joined at their apices. Th… Web59K views 10 years ago.
