By looking at the range of isotopic variations in terrestrial and meteoritic samples, a LLNL scientist and collaborators have figured out that Earth and Mars formed by collisions of planetary embryos originating from the inner solar system.
☄️ Rocky planets may have formed by two fundamentally different processes, but it is unclear which one built the terrestrial planets of our solar system. The planets formed either by collisions among planetary embryos from the inner solar system or by accreting sunward-drifting millimeter-sized “pebbles” from the outer solar system.
