According to one of the most widely accepted ideas, Moon originated from a large amount of debris left over from a planet the size of Mars colliding with Earth when it was much younger.
But according to a recent study, there's a chance that fragments of the planet that collided with Earth are still inside our world.
Large low-velocity provinces (LLVPs) are the term used to describe the blobs. Their origin is the next point of inquiry.
These blobs may be the remnants of the old planet that collided with Earth billions of years ago to create the Moon, according to a study
Theia was the name given to the smaller planet that collided with Earth, although neither meteorites nor the asteroid belt contain any evidence of it.
The Moon is thought to have formed from the impact's leftover debris after the majority of Theia was absorbed by early Earth, creating these "LLVPs," according to the researchers.
Two structures that appeared to be close to the Earth's core contained iron concentrations that were abnormally high.
Caltech researchers modeled various scenarios about the chemical composition of Theia and its influence on Earth. These simulations verified that the Moon and the LLVPs may have formed from the collision's mechanics.
The Moon might have formed from a mixture of the other collision debris and some of Theia's mantle fusing with Earth's.
