The reason we can't see the other side of the Moon from Earth lies in a phenomenon called 'tidal locking'. Here's an explanation:
Why We Only See One Side of the Moon
1. The Moon’s Rotation and Orbit
- The Moon rotates on its axis, and it also orbits Earth.
- However, the time it takes for the Moon to complete one rotation on its axis is the same as the time it takes to orbit Earth --'27.3 days'.
- This synchronization means that the same side of the Moon always faces Earth.
2. How Tidal Locking Happens
- Tidal locking occurs due to gravitational forces between the Earth and the Moon.
- Early in the Moon’s history, its rotation was faster, but Earth's gravity created "tidal bulges" on the Moon.
- Over millions of years, these bulges caused the Moon’s rotation to slow down until it matched its orbital period.
3. The Far Side of the Moon
- The side we can’t see from Earth is often called the "far side" or "dark side" of the Moon, though it’s not actually dark--it gets sunlight just like the near side.
- We first saw it in 1959 when the Soviet Luna 3 spacecraft captured images of the far side.
Fun Facts About the Far Side
- The far side has more craters and fewer maria (dark basaltic plains) than the near side.
- It’s home to the 'South Pole--Aitken Basin', one of the largest impact craters in the solar system.
