big bang
Scientists believe that the Earth was formed around 4.6 billion years ago through the accumulation of dust and gas in the early solar system. This age estimate is based on radiometric dating of meteorites and rocks from Earth.
The moon was thought to have formed 4.527 billion years ago, when a large planetoid the size of mars collided with the earth, as the solar system was still in its infancy. The remains of this impact went into orbit around the Earth, forming into the moon we have today.
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
