(TheWeatherSpace.com) — The moon may have been hit by a second moon orbiting the Earth which explains why the two sides are different.
The ‘dark side’ of the moon is never shown at Earth and it rotates with the rotation of Earth so precise that we may never see it.
But spacecrafts have seen the other side of the moon, which has been discovered to be different than the Earth-facing side.
Scientists have discovered through an animation that a collision between Earth’s moon and a companion moon that was 750 miles wide and about 4 percent the lunar mass, may have been response for the different terrains.
The impact would have pushed an underground source of magma toward the near side, explaining why rare-earth metals and radioactive potassium, uranium, and thorium are concentrated best near the crust there.
