The theory of 'Giant Impact' is a hypothesis how the process of formation of the moon. Scientists theorize, the Moon formed by joining the pieces of the Earth is broken when it collided with a young celestial bodies the size of the planet Mars.

Any evidence supporting this hypothesis are examples of rocks taken by astronauts during a visit to the Moon. Of rocks, indicated that the Moon's surface before it is liquid and the possibility of having a small core of iron with a lower density than the Earth.
The celestial objects hit the Earth known as Theia, named after the Greek goddess, who is the mother of Selene, goddess of the Moon.
According to the Giant Impact theory, Theia formed along with lainnay planets in the solar system some 4.6 billion years ago. He circled the Sun in roughly the same orbit with Earth about 60 degrees ahead or behind the Earth.
Stability in circling the Earth and then disrupted because of Theia and grow beyond the maximum limit of 10 percent the mass of planet Earth. As a result, the force of gravity makes Theia abandon positions and close to the Earth's orbit and collide with each other.
According to astronomers, a collision between Earth and Theia took place around 4.53 billion years ago, or about 30 to 50 million years after solar system formation. However, from recent evidence, indicated that the collision took place more slowly, which is 4.48 billion years ago.
