Earth Once Had Two Months?

A new theory suggests that Earth was at one time a second month, less, he died in a collision with the slow “his older sister.”Researchers believe that this collision would explain the mysterious existence of mountains on the distant moon.

Scientists argue that the relatively low speed collision was crucial in adding material rarely seen new monthly hemisphere.

For decades, researchers have tried to understand why the moon visible from Earth is flat and cratered, while the “dark” has craters and mountain ranges up to 3,000 m altitude.

Various theories have been proposed to explain these differences.

Recently, researchers have argued that the Earth was hit by a planet the size of Mars in about four billion last year. Debris resulting from the impact were aggregated and led to the formation of the Moon.

But scientists say that another body monthly, smaller would be composed of the same material and remained locked in a gravitational field located between the Earth and Moon.

Doctor Martin Jutzi at the University of Bern, Switzerland, said that after millions of years has been caught between the two planets, the moon came a little collision course with “her older sister”, with a slower three kilometers per second.

Scientists argue that the impact would have led to the accumulation of bark material would be redistributed monthly and also that magma is on the visible moon. This idea was supported by observations from the Lunar Prospector space vehicle.

Researchers consider that the only way to prove this theory is to compare their models with the detailed structure of the Moon, this information may be obtained from NASA, is about data collected by Lunar Reconnaissance Orbiter probe.
