The Moon has a bonanza of metals like iron and titanium deep below its surface, according to NASA, raising questions over a long held formation theory. The leading theory claims that the Moon formed out of the wreckage created when a Mars-sized planet called Theia collided with the young Earth 4.5 billion years ago. Dr Heggy said improving our understanding of how much metal the Moon actually has allows scientists to gain a deeper understanding of its formation. This fine dust in the craters is the remains of ejected materials forced up from below the Lunar surface during meteor strikes, the team said. By understanding how the Moon formed, and in fact how the more than 200 other moons in the solar system formed, we can gain a deeper understanding of how planets form, according to the team.
