Collisions with small planets over hundreds of millions of years Explain why it is so big

Scientists have always known that Earth has a long history of resistance to celestial violence, but now they think that the same test explains why our planet is as big as it is. That's according to a new study published in the journal Nature Geoscience that argues that the way scientists calculated what the Earth got from that violence was flawed.

The disaster here began after the formation of the moon, during some kind of very large and messy event (scientists are still evaluating some theories about precisely what happened). As if that were not traumatic enough for a young planet, for hundreds of millions of years after the formation of the moon, the Earth was bombarded by what scientists call planetesimals, nicknamed the "building blocks" of the planets.
