Theory Of planetary seeding 28/02/2013 There are many different views and theories presented concerning the creation of our planet, its spin and satellite.

I believe, all the theories I have read or heard put forward by many and numerous luminaries are all incorrect, a new simpler view must be taken of the formation of our planet, its unique axial spin and the satellite that effects this. My theory also give's credence to the evidence that liquid water was delivered quickly and early in our planets formation.

There is little study into how earth's sole satellite formed. There are some early studies using computer simulations and low pressure rifled impactor's. Nothing though that will remotely show anything that may resemble our own planet and its early indications. I would like to present a theory that may answer a few of these questions. Whilst staying true to many facts we hold true about the formation and subsequent indications our planet has shown.

If we take for granted the evidence that the early solar system was a massively busier place than it is now. This early solar system would have had many, medium sized objects, similar in size, too present day mars. Some of these young planets, would be quite large with stable orbits, especially those, closer to their host star. As you travel further and further away from the host star, these minor planet would become smaller, rockier and heavily iced, similar in fact too Pluto. Not only this, being further from its host star, these smaller planet's become the gravitational targets, of any, huge gas giant or large planets in the host system. These behemoths usually ,and regularly, knock or move, interact or plain destroy other solar system residents.

The scene is now set for our earth and its satellites creation. A slow moving, molten iron planet with little spin and no satellite, an early earth. The heat of our early solar system helping to keep, the young earth, almost completely molten. Then, from the deep, cold solar system, having been in the deep freeze of the outer system for hundreds of thousands of years. A small rock and ice planet. Moved by the gravitational forces of Neptune, Saturn and Jupiter or a combination of them all. Similar in size and composition too Pluto, it hurtling through space with massive force and intent. Its solar orbit so damaged, it brought it closer and closer to other, more settled, solar bodies. By the time it impacts, it has already made several thousand passes, orbiting closer to the sun every time. Each orbit bringing ,the inevitable, ice melt and refreeze as the planet drifted, once more, away from its host star. Then came the fateful orbit of the ice and rock planet. After making another pass of its young star once more, it came around into the direct path of our earth. The two planets came together in a huge, cataclysmic impact. Both planets merge into one, the rocky remnants of earth's, would be assassin, smashed into near earth orbit. Rock, water and rocky a satellite. All the things needed for a molten metal planet too transform into a rock and water covered, harbinger of life. The now magnetic core, of the now spinning, early liquid metal planet, blanketing and protecting the early life. Primordial life, that had just been delivered by the earth's, would be killer.

We are left with an early planet that has a molten metal core, a rock covered mantel and is drenched in liquid water. It is spinning slightly off its axis, resulting from the impact with the earths rock and ice assassin. The remnants of which, have come together and formed our, now familiar, rocky friend.
