… New theory. "The Moon, and the question of how it was formed, has long been a source of fascination and wonder. Now, a team of Israeli researchers suggests that the Moon we see every night is not Earth's first moon, but rather the last in a series of moons that orbited Earth in the past. The findings by the team of researchers from the Technion-Israel Institute of Technology and the Weizmann Institute of Science are published in Nature Geoscience. The newly proposed theory by researchers Prof. Hagai Perets, of the Technion, and Weizmann Institute Profs. Raluca Rufo (lead author)and Oded Aharonson, runs counter to the commonly held "giant impact" paradigm that the moon is a single object that was formed following a single giant collision between a small Mars-like planet and the ancient Earth. "Our model suggests that the ancient Earth once hosted a series of moons, each one formed from a different collision with the proto-Earth," said co-author Prof. Perets. "It's likely that such moonlets were later ejected, or collided with Earth or with each other to form bigger moons." To check the conditions for the formation of such mini-moons or moonlets the researchers ran 800 simulations of impacts with Earth…" Main page link Amicalement Armand |

If I recall correctly, the predominant theory for how the far side of the moon formed is that the moon and another large earth moon merged/collided. I don't think that many such smaller collisions forming the current moon would be particularly paradigm shifting, but it is pretty interesting. |
