Scientists think this probably happened and that the "planet" was about the size of Mars. However, it was several billions of years ago and the object that hit Earth is not usually given a name.

Why does the Earth have 1 moon?

the Earth has a moon because while the earth was just a new planet, still forming, a big meteor hit earth and made a big dent somewhere... debris dust, and big chunks of earth flew into space. the pieces wandered around earth, the gravitational pull of earth kept it in an orbit. as the chunks and pieces flew around, they clumped together getting bigger and bigger. within weeks, our moon was formed. that's why the moon changes the tide level


Earth's moon hypothetically was a portion of earth when it was hit by an asteroid how was this possible?

if a meteor hit earth and a piece of earth (the moon) chipped off. earths gravitational pull could be sufficient to make the moon orbit around the earth.
