How our MOON (lunar) came to be

The obstetrician of the moon is the giant asteroid "Theia".

After his collision with the Earth only 24 hours passed up from the crash wreckage was our Lunar!

Had the earth just a heavy iron core and a shell made of lightweight silicates - - some four billion years scraping a Mars-sized Hirnmelskörper called "Theia" the earth side and brought them to burst. The majority held, but which hurled rocks formed along with the crumbled "impactor" Theia a kind of ring around the young Earth. The result looked like the Saturn today - but only for a day. In no time, after only 24 hours, the rock debris have again come together and formed a new celestial body: Luna. Earth's moon.

For example, scientists are now the emergence in our cosmic companion. For after the Apollo astronauts and Soviet Luna probes total of 382 kilograms of rock brought back from the moon is clear: the material is similar in nature to the very strong on the earth. So there must be a common origin. It is unclear why today we can not find any remnants of this collision. Because the rock masses of the earth would be back by this disaster completely melted and blended have. But it is nothing to notice.

Have in the early 1990s, some experts deal with the question of how it would look like on Earth, there would be no moon. Results of all studies:

Then there would be no life. The astronomer Jacques Lasker with the Bureau de Longitudes in Paris recognized by computer simulations show that the gravity of the moon stabilizes our world - without them, would tilt the Earth's axis every few million years by up to 85 degrees. Under such extreme climatic conditions could not form a higher life. The astronomer Jack Wisdom of the Massachusetts Institute of Technology (MIT) found similar results in studying the Martian climate (around Mars flies While not a real moon, but two planetary fragments that are not sufficient to stabilize its axis).

The astronaut Neil F. Comins describes in his book, "What would the Earth without a moon?" * Also have far reaching consequences. There would only be triggered by the gravity of the sun "small tides," which are much weaker than the lunar tides. Due to the lower movement of the water, the oceans would absorb less mineral nutrients - bad for the fish, there were no major flooding areas along the coasts - bad for all living creatures in this room, for example crabs.
