Moon may have formed in only five hours, new models indicate
Researchers from the University of Arizona and the Southwest Research Institute utilized simulations that account for rock density to propose that the Moon took a mere five hours to come into existence. This theory suggests that a massive collision involving a protoplanet named Theia 4.5 billion years ago likely triggered the quick formation of our satellite. This rapid development process offers a potential explanation for why the Earth and the Moon share such similar chemical makeups.
