Nebular hypothesis earth moon formation originA collision between two proto-planets with unique isotopic compositions is thought to have created the Earth-Moon system.

However, explaining why the Earth and Moon don’t then themselves have unique isotopic characteristics, as most planets in the Solar System do, has been challenging.

To resolve this, some scientists have proposed a high-energy collision model in which isotopes between the two were nearly equally mixed upon impact; any differences, then, may have resulted from subsequent impacts to the rocky planets, later in time.

Not really practically likely but run with this framework as everything needs some foundations to build on.

“Our analysis showed a 3- to 4-ppm (parts per million) difference between the oxygen isotopic concentrations of the lunar rocks and the terrestrial basalts, but no significant difference between the lunar samples and terrestrial olivine, a common mineral in Earth’s subsurface,” the scientists explained.

moon earth formation water impactTaking aubrite meteorites as a candidate impactor material, we show that the giant impact scenario involved nearly complete mixing between the target and impactor...

The now classic formulation of the Moon-forming giant impact hypothesis envisaged an oblique impact between the proto-Earth and a Mars-sized body... However, with a sole exception, high-precision studies have failed to detect a difference between Earth and the Moon.

To explain this apparent discrepancy, it has been proposed that isotopic equilibration took place within a post-impact, melt-vapor disc. Studies of silicon and titanium isotopic variation have also revealed no differences between Earth and the Moon. In addition, tungsten isotope studies indicate that Earth and the Moon initially had a similar 182W composition.

The fact that both tungsten and titanium show no isotopic differences between Earth and the Moon is potentially significant because both are very refractory elements and, thus, unlikely to have been significantly affected by the proposed post-impact equilibration.

... On the basis of this assumption, our data indicate that post–giant impact additions to Earth could have contributed between 5 and 30% of Earth’s water, depending on global water estimates.

Consequently, our data indicate that the bulk of Earth’s water was accreted before the giant impact and not later, as often proposed.

planetary formations theories waterThis demonstrates how efficiently the two colliding planets mixed, and also places strict limits on the types of material that could have been added to the Earth afterwards.

What’s even more fascinating is that, because this worked for the Earth and the Moon, it must also work for planets beyond our Solar System.

Exoplanets with water on their surfaces may be much more common than we previously thought. And where there’s water, there could also be life.
