The Moon's Gradual Drift from Earth
This animation shows how the Moon has moved away from Earth over time.
The Moon formed around 4.5 billion years ago, likely from debris left after the "Giant Impact" between Earth and a Mars-sized planet named Theia. Initially, the Moon was a hot, glowing red object in the night sky. Scientists estimate that the Moon was receding from Earth at a rate of about 20 cm per year back then. Today, it continues to move away, but much more slowly—only 38 millimeters per year.
