    Answer: the following five theories propose to explain the moon formation;

    1. Capture

    2. Fission

    3. Conformation

    4. Colliding planetesimals

    5. Giant impact

    Explanation:

    Capture: some researchers suggest that the moon originally formed elsewhere before being grabbed by the earth gravitational pull.

    Fission: this thought is from Charles Darwin's son George, he explain that the material that formed the moon was ejected into space by a molten, fast spinning earth in the early days of the solar system.

    Co-formation: It was also possible that the moon formed alongside Earth 4.5 billion years ago, coalescing from dust and gas in the same part of our solar system's protoplanetary disk.
