This is how the Moon was formed...mp4

The most widely accepted theory, the 'Giant Impact Hypothesis,' and a recent scientific simulation video
Key features of the Giant Impact Hypothesis
• Timing of collision: Approximately 4.5 billion years ago, during the formation of the solar system
• Collision targets: The proto-Earth and a Mars-sized planet named 'Theia'
• Formation process: Debris and material melted by the collision orbited the Earth and eventually coalesced to form the Moon
• Scientific evidence: Analysis of lunar rocks brought back by the Apollo missions supports this hypothesis, showing that the Moon's titanium isotope ratios are very similar to Earth's.
• Recent research trends: According to simulations by US researchers and others, it has been suggested that depending on the state of Theia, the foundation of the Moon may have formed just a few hours after the collision.
