WebSep 7, 2024 · Double planet (also called the condensation hypothesis): The moon and the Earth formed together at about the same time.; Capture: The Earth's gravity captured the fully formed moon as it wandered by. Fission: The young Earth spun so rapidly on its axis that a blob of molten Earth spun off and formed the moon.

WebThe fission hypothesis has some new evidence that suggests it might be possible, however problems exist with the fission hypothesis regarding the angular momentum … WebCapture theory suggests that the Moon was a wandering body (like an asteroid) that formed elsewhere in the solar system and was captured by Earth's gravity as it passed nearby. In contrast, accretion theory suggested that the Moon was created along with Earth at its formation. Finally, according to the fission scenario, Earth had been spinning ...
