Correct mathematical description of incoherent Earth revolving on the orbit around the Sun leads to unequivocal and logical mechanism of Moon’s origin. Before 4,6 Gyr fast rotation of Earth caused outburst of the first inner core of the Earth. With fast rotation of the Earth (Td=4h) the solid ferro-nickel sphere broke the thin mantle and was centrifuged to the orbit round the Earth. On the Earth’s orbit the gravity force of this ferro-nickel sphere was dominant over other fragments of Earth. These fragments were pretty fast 'accumulated' on the orbit and created the Moon. Presence of the Moon on the orbit slowed down the rotation of Earth above the limit value of 4 hours; that is why there was no other outburst of inner core. The plate tectonics drive mechanism and the drift of continents are the direct continuation of the Moon’s formation mechanism. http://independent.academia.edu/TadeuszTumalski/Papers/436138/Earth-Moon_System_The_Origin_Development_and_the_Future
Occasional Neptune perturbations can deflect SKBOs to planet-crossing orbits. Some of these bodies may find their way to the inner solar system, where ...
