Small 'moonlets' may have collided to form the Moon as it has been seen today. The newly proposed theory by researchers at the Technion – Israel Institute of Technology and Weizmann Institute of Science in Israel 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 Earth.Hagai Perets from the Technion said that the model suggests that the ancient Earth once hosted a series of moons, each one formed from a different collision<br/>with the proto-Earth. <br/><br/>Perets opined that it is 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 and simulated about 800 simulations of impacts with Earth.<br/><br/>The tidal forces from Earth could cause moons to slowly migrate outwards – the current Moon is slowly doing that at a pace of about one centimetre a year.<br/>
