Moon Rocks Help Support Theia Collision Theory - The Moon was most likely formed by a collision between the Earth and a planet-sized object that took place roughly 4.5 billion years ago, a team of German scientists report in research published Friday by the journal Science. That object was a planetesimal named Theia, Dr. Daniel Herwartz of the University of Goettingen and his colleagues explained in their study. Image Credit: NASA | via redOrbit.com
