​There have been new simulations about the early formation of the Solar System. Some of them have been done around the relationship between the Earth and the Moon. There was a time when the Earth could’ve been part of a big squishy doughnut of rock in the early Solar System.

This was about 4.5 billion years ago when an object hit the Earth and the​ ​Moon appeared shortly thereafter. One new simulation, as reported by ​Science News, suggests that the moon formed when the hot cloud of rotating rock vapor in the early Solar System with large planetary objects, or something like them, smashed into each other at incredible velocities.

The radiation in this cloud mixed with planet matter can send huge tumbling rocks hurtling. The moon, apparently, “grew from fragments in this hot, high-pressure environment, with a bit of iron solidifying into the lunar core.”

Within only a few hundred years, which is less than a blink of an eye in cosmic time such as the formation of the Solar System, an almost completely formed moon came out of the cloud and condensed.

The Moon apparently spent sufficient time in the cloudy mixed up material of the doughnut to acquire similar ingredients, to create similar ingredients, as the Earth.

The simulation, and note importantly that this is only a simulation but still an important contribution to the theoretical underpinnings and comprehension of the formation of parts of the early Solar System, contrasts with the current explanation, which is that a protoplanet about the size of Mars, called Theia, collided with Earth and that the Moon formed from the distant pieces of it out of the collision.

The contents of the Earth, in the current explanation, would mean that the Earth should have a different set of constituent elements in it than the Moon, but do not, which contrasts with the main explanation of a Theia and proto-Earth collision in the early Solar System.

The Earth’s and the Moon’s constituent elements are highly similar, which supports the notion that they come from the mix of various elements in the gaseous, radiative, rocky, donut cloud of the early Solar System.
