An international team of planetary scientists determined that the Moon formed nearly 100 million years after the start of the solar system, according to a paper to be published April 3 in Nature. Speed Dating Hong Kong
This conclusion is based on measurements from the interior of Earth combined with computer simulations of the protoplanetary disk from which Earth and other terrestrial planets formed.mess up my intentions
The team of researchers from France, Germany and the United States simulated the growth of the terrestrial planets (Mercury, Venus, Earth and Mars) from a disk of thousands of planetary building blocks orbiting the Sun.hold back these tears I cry

By analyzing the growth history of Earth-like planets from 259 simulations, the scientists discovered a relationship between the time Earth was impacted by a Mars-sized object to create the Moon and the amount of material added to Earth after that impact.cherish baby lovely blush

Augmenting the computer simulation with details on the mass of material added to Earth by accretion after the formation of the Moon revealed a relationship that works much like a clock to date the Moon-forming event. star shine in black hole

This is the first "geologic clock" in early solar system history that does not rely on measurem.五道涙
