Scientists have claimed the moon is made up of lots of smaller moons. Originally it was thought that our lunar buddy came from a huge piece of earth that flew off after a massive collision with something spacey.
Not so much, as The Independent reports, the moon could be ‘the result of a series of cosmic collisions’. It is believed that over millions of years, a multitude of Earth fragments broke off during collisions, and fused together to create the moon, a theory first suggested in the 1970s.
Co-author Ralaca Rufu claims these small moons were able to merge by ‘crossing orbits’.
Using 1,000 different computer simulations of ‘collisions between a proto-Earth and embryonic planets called planetesimals, smaller than Mars’, researchers concluded that 20 impacts could have done the job, reports telesur.
The researchers claim this is the reason the moon is made up of earthly material, and not some mysterious compound.
