The Moon may have been formed by a collision between Earth and an object that was strikingly similar in composition to our own planet.
This could help resolve why Earth and Moon rocks are a great deal more comparable than we would anticipate from this "monster effect speculation".
The study is one of three distributed in the prestigious diary Nature.
Two further research papers in the issue report inconspicuous, beforehand concealed contrasts in lunar rocks.
Researchers say they paint a predictable - and much clearer - photo of our satellite's history.
The displaying study, done via analysts from Israel and France, unequivocally reenacts the turmoil of the early, internal Solar System and evaluates the assortment of impacts that may have happened.
In its initial stages, the proto-Earth would have been subjected to a string of ruthless crashes with other wannabe planets.
As indicated by our best comprehension, the final one of these was a disastrous tangle with a planetary body only ten times lighter than Earth - and the subsequent flotsam and jetsam in the long run amassed together to make the Moon.
The issue is that the vast majority of what turned into the Moon ought to have originated from the faker - and in light of our current learning of what was flying where around then, that fraud was thought to be an altogether different kind of planet.
"So if the impactor had an alternate arrangement from the Earth, we ought to anticipate that the Moon will have an alternate sythesis," Dr Hagai Perets, one of the study's creators, told the Nature podcast.
However this is not the situation.
"They are very nearly indistinguishable. This is one of the real difficulties for this truly lovely titan sway speculation," said Dr Perets, from the Technion-Israel Institute of Technology.
This is the reason a study stood out as truly newsworthy in 2014 when it pinpointed some small contrasts in the middle of Earth and Moon rocks.
What Dr Perets and his partners found in their new recreations was that the impactor planet may, actually, have been made of shockingly comparative stuff to the Earth - leaving just the kind of unobtrusive contrasts that we do see in lunar material.
