The protoplaneet that the early earth collided, and according to the most accepted theory is the moon formed, probably had an earth-like composition, it appears from simulations that Wednesday in Nature.
The research describes how the agreements between the mantle of the earth and the moon arise. If the moon indeed formed by a collision between the proto-earth and a planeetachtige the size of the current Mars, then it would be logical that the largest part of the material of the moon consists of material of the impacting object. Strangely enough, seem to be the monsters of the moon suspiciously on the composition of the earth’s crust. Other bodies in our solar system have a very different composition.
From the twisted simulations of areas where planets are formed, it appears that different planets during the same simulation are formed, of different compounds. It was striking that large objects significantly more often, stocking up on planets with a similar composition, so the nearest composition between the moon and earth may be a natural result of that late, great impact.
