The Theia hypothesis is the current leading hypothesis to explain how our moon was created. Both Earth's mantle and the moon's surface have indistinguishable oxygen isotope ratios, which leaves the earth–moon system as more similar in O isotopes than any other two bodies in the solar system
However, new research suggests that the Earth's mantle (mostly olivine) doesn't resemble the moon's surface (also olivine, but mostly orthopyroxene) as much as we thought.
Does this change our view on the Theia hypothesis?
Sub question: were others moons (for instance the Galilean moons) also created partly with material of their host planet?
