The Moon's orbit is tidal-ly locked to Earth, which means it takes the Moon about 27.3 days to complete one orbit. But here's a quirky fact: the Moon is also slowly moving away from Earth at a rate of about 1.5 inches (3.8 centimeters) per year! That's because the tidal interactions between Earth and the Moon are causing the Moon's orbit to increase in size over time.
This has some pretty interesting implications - for example, the Moon was much closer to Earth billions of years ago, which would have made for some pretty extreme tides! It's cool to think about how the Earth-Moon system has evolved over time, and how it will continue to change in the future.
