Scientists have discovered that Theia, the impactor that formed the Moon, likely originated from closer to the Sun than Earth, based on isotope evidence from lunar rocks, Earth samples, and meteorites showing that Earth and the Moon are chemically almost identical, which supports the giant-impact theory and suggests Theia's material came from the inner solar system, possibly including a previously unknown type of ancient planetary building block.

Did Theia Come From Closer to the Sun Than Earth?Added:
The object that made the moon may have come from even closer to the sun than Earth. Scientists compared iron and other isotope fingerprints in moon rocks, Earth samples, and meteorites.
The shock was this: Earth and the moon are chemically almost twins, exactly what a giant impact predicts.
Models say most of Theia came from the inner solar system, and some of it may be from a world type we have never found.
