Earth’s Mantle May Contain Evidence of a Planetary Collision that Formed Our Moon

<p>Astronomers have several theories on why Earth has a moon, although one is much more widely accepted than the others. The first is known as the fission theory, which states that the Moon may be a piece of Earth that broke off during its formation due to speedy rotation. Similarly, another theory called the co-creation theory suggests that the Moon formed at the same time as Earth out of the same material. Both of these theories tend to be overlooked, as the Moon&rsquo;s composition is not similar enough to Earth&rsquo;s.</p> <p>Another theory of lunar formation is the capture theory. The basic idea is that the Moon was already formed and simply pulled into orbit by Earth&rsquo;s gravity during a close encounter during the formation of the solar system. The main flaw with this theory is that capturing an object as large as the Moon would&rsquo;ve been essentially impossible.</p> <p><a href="https://beccajean.medium.com/earths-mantle-may-contain-evidence-of-a-planetary-collision-that-formed-our-moon-341d1365d8e6"><strong>Click Here</strong></a></p>
