Earth wobble theory

The Earth's rotation around its axis, and revolution around the Sun, evolve over time due to gravitational interactions with other bodies in the Solar System. The variations are complex, but a few cycles are dominant. The Earth's orbit varies between nearly circular and mildly elliptical (its eccentricity varies). When the orbit is more elongated, there is more variation in the distan… WebFor centuries, the Moon has been a constant companion in the Earth's night sky, lighting up our world with its reflected sunlight. However, recent scientific discoveries have revealed that this celestial object is slowly drifting away from us, at a rate of 3.8 centimeters per year. This gradual shift is having a significant impact on our planet ...
