Introduction
There are about three theories that show how the Moon was formed. These theories try to explain as to how the Moon came about using the composition of the Moon as the basis for the study. Scientists have conducted experiments at the moon’s surface as well as they have given attention to the inner rocks that are found below the surface to see if at all they match the composition of the rocks here on earth.
In the first theory, scientists believe that in one theory, the moon was captured by the Earth. In this theory, they believe that maybe the moon’s orbit was going in the opposite direction among other heavenly bodies and its close proximity to the earth’s gravity allowed it to be captured by the gravity of the earth. However, this theory does not explain why the Moon has composition close to the composition of the earth’s surface. As per astronomers, the captured steroids do not have a spherical shape instead they exhibit an oval shape.
In the second theory, the moon was formed pretty much the same time as the earth. They say that they were formed from the primitive solar nebula at which each body condensed close to each other to form the moon and earth. This however does not explain how the composition of the moon and the earth came to be so different despite being made of the same substance.
The third theory tells us that a huge heavenly body possibly the size of Mars collided with the earth and Moon was formed out of the debris that was ejected from the opposite side. When the material ejected cooled, it formed the Moon. This theory explains the composition of the moon. However, we should not worry that the impact affected the planet since the mass of the earth cooled and balanced itself.
