Did you know the Moon is slowly drifting away from Earth? Each year, our closest celestial neighbor moves about 1.5 inches farther from us. Scientists have studied this fascinating phenomenon for decades.
How Do We Know the Moon Is Receding?
Researchers measure the distance to the Moon using lasers. They bounce these lasers off mirrors that astronauts and space probes left on the lunar surface. This technique gives us incredibly precise data about the Moon’s position. 
Why Is the Moon Moving Away?
The main reason for this drift is tidal forces between Earth and the Moon. As Earth rotates, it pulls on the Moon with its gravity, and vice versa. Over millions of years, these forces transfer energy and gradually push the Moon into a slightly higher orbit. This process also slows down Earth’s rotation very slightly.
What Does This Mean for Our Planet?
While the Moon’s slow escape won’t affect us immediately, it has fascinating implications for Earth’s tides and the length of our days in the far future. This celestial dance reminds us of the dynamic relationship between our planet and its only natural satellite.
