At the end of the formation of the Solar system collided with two hot planets.
Scientists from the United States explained how the Moon was in its place.
According to the current theory, at the end of the formation of the Solar system collided with two hot planets. Future Land dropped quickly. From it was formed the Moon. This is evidenced by the fact that the composition of the Earth and its satellite are strikingly similar. The angular momentum of the Earth-the Moon was dissipated by tidal forces between these objects and began working in the opposite direction.
However, this theory does not explain why the moon’s orbit is tilted five degrees from the equator of our planet. If it is condensed from a disk of material orbiting the equator, would be in orbit above it. Lead authors of the new study – Sarah Stuart from University of California, Davis and Matija Chuk of the SETI Institute in mountain view – offered model proving that the collision was much more powerful than thought.
The material of the Earth and struck him in the body mixed up, so the moon is similar to earth’s composition. Future the satellite was moving away from Earth until it reached the point called the “transition Laplace”. There the force of the earth influence the moon has become less important than solar gravity. Part of the angular momentum of the system Earth-Moon was handed over to the system Earth-Sun.
It didn’t affect Earth’s orbit around the sun, but turned our planet into a vertical position. The orbit of the moon was under a considerable inclination to the equator. For tens of millions of years it slowly moved from the Ground until it reached the second point – the so-called “Cassini transition”. Then the tilt of the moon fell to five degrees, and she took his place.
“The new theory elegantly explains the orbit and composition of the moon based on one giant blow, says Sarah Stewart. No additional interim actions do not need to receive the result.”
Previously, scientists claimed that the Moon formed as the result of a frontal collision of the Earth with the planet Theia after about 100 million years after the formation of the globe.
