Detailed explanation-1: -Scientists have proposed many ideas for how the Moon formed. A leading contender, the Giant Impact theory, speculates that when Earth was a young planet and just beginning to form, it was hit by another emerging planet named Theia, located nearby.
Detailed explanation-2: -In the impact hypothesis, Mercury is a gravitationally bound remnant after bulk ejection of a portion of the mantle. Moderately volatile elements recondense as silicates as the planet cools and there is no expected fractionation between condensing elements.
Detailed explanation-3: -The prevailing theory on Moon formation, called “The Giant Impact” hypothesis, proposes that the Moon formed from the debris of a collision between the Earth and a planetary body called Theia, which was about the size of Mars (slightly more than half the size of Earth).
