The Moon is gradually drifting away from Earth at a rate of approximately 3.82 centimeters (about 1.5 inches) per year, a phenomenon that has significant implications for our planet
This drift is primarily due to gravitational interactions between the Earth and the Moon, which affect tidal forces and the rotation of the Earth.
Impact on Earth's Rotation As the Moon moves away, it is causing the length of a day on Earth to increase. Current estimates suggest that in about 200 million years, the average day could extend to 25 hours.
This change is analogous to a figure skater slowing down as they extend their arms—similarly, as the Moon recedes, Earth's rotation slows down due to the conservation of angular momentum within the Earth-Moon system
The Moon's retreat also affects Earth's geological structure and climate. The gradual lengthening of days can influence various geological processes and climate rhythms, known as Milankovitch cycles
which are linked to the distribution of sunlight on Earth and can impact long-term climate patterns
While the Moon is not expected to leave Earth, its continued drift will eventually lead to a state where both bodies could become tidally locked, resulting in Earth always showing the same face to the Moon.
