Titanium Isotopes Provide Clues to Lunar OriginTitanium Isotopes Provide Clues to Lunar Origin
The Moon may have formed by the impact of a Mars-sized object with Earth. Planetary accretion models suggest that the impactor and Earth would have had different isotopic compositions… …but titanium has the same isotopic composition in both Earth and Moon. The dynamics of planet formation and of the giant impact need a closer look.
