One theory of the moon's formation is The Giant Impactor theory. This theory states that a planetesimal crashed into the Earth just after it was created. Debris was formed from this collision and this "space junk" eventually stuck together to form the moon.
The Great Impactor Theory
Other theories include the Fission Theory, which states that the moon was once part of the Earth and somehow broke off just after its formation. Also, there is the Capture Theory, which shows an opposite point of view. This theory says that the moon was formed somewhere away from Earth and eventually, under the influence of Earth's gravitational field, came to orbit around our planet. Finally, there is the Condensation Theory, which explains that the Earth and the moon were both initially formed when the solar system was being formed from its original nebula.
