Study: Results form the Moon Is a Collision

In the first collision of two orbiting the Earth to explain why the current month returns and the texture is slightly different from the two sides, said the scientist.

The study, published in the journal Nature, indicates that the Moon was once accompanied by a smaller satellite. Both were around the Earth about 4 billion years. Similarly, quoted by Reuters on Thursday (08/04/2011).

"But because both the Moon continues to evolve, as well as the influence of the Sun's gravity, making even the stability of both the satellite is unstable, so eventually the collision occurred," says Erik Asphaug, a planetary scientist at the University California.

Described by Asphaug, that after the process 100 million years, eventually crashing into a smaller moon of each month. Collision of two satellites now explains how the moon's surface has two different faces: the thin and thick.

Collision of two months is also known as the contributing factors for the current month and the oval a bit unusual. However, scientists acknowledge that the research would be the Earth is not easy.

Asphaug also said that elements of the collision are still a hot liquid material, until he stood in the cooling process below the surface of the moon.
