Why Do We See Only One Side Of The Moon? | BYJU'S Fun Facts
The Moon's Dance
This video explains how the moon moves around the earth and why we can only see one side of it.
The Dark Side of the Moon
- The dark side of the moon is always hidden from Earth.
- If the moon were only revolving around the earth and not rotating on its own axis, all of its sides would still be visible from Earth.
How the Moon Moves
- The moon rotates on its own axis and also moves around the earth in a movement called revolution.
- The moon rotates exactly one time while tracing one circle around the earth.
- This way, one of its sides is always facing Earth while the other one is always hidden.
Why We Can Only See One Side
- Earth's gravity pulls the moon towards itself in such a way that this one side cannot move away from Earth.
- Over time, Earth's attraction has caused the moon to become oblong in shape, making it easier for Earth to pull it back whenever it tries to face away.
- It's not really that the moon is hiding its dark side from Earth; it's that Earth is not letting the nearer side move away.
Conclusion
- The moon attracts Earth as well.
