Why We See Only One Side Of Moon
Olivia Luz
Let s conclude all the amazed reasons why do we see only one side of moon always.
The reason why only one side of the moon is visible from earth because the moon s gravity is tidaly locked by the earth s gravity. Nope not by chance it s pure physics. It s just that the amount of time it takes the moon to complete a revolution on its axis is the same it takes to circle our planet about 27 days. There are two main reasons for this.
Only one side of the moon ever faces us because earth s force of gravity on it is not uniform. First the moon s orbit around earth is elliptical not circular so its rotation is sometimes ahead and sometimes behind its orbital motion. Only one side of the moon is visible from earth because the moon rotates on its axis at the same rate that the moon orbits the earth a situation known as synchronous rotation or tidal locking. This is related to our ocean tides and a lengthening of days o.
You may have heard references made to the dark side of the moon. This popular term refers to the fact that the same physical half of the moon the near side is always facing earth which in turn means that there is a far side or so called dark side that is never facing earth and can only be seen from space. Tidal locking is the reason why do we see only one side of the moon the simple answer is that we only see one side of the moon because the moon rotates around the earth at the exact same angular speed in fact it s not exactly true we ll talk about it later too as it rotates around its own axis so that the same side of the moon is constantly facing the surface of the earth. Our lunar companion rotates while it orbits earth.

Moon s speed revolving around the earth and spinning on its axis is similar because moon s center of gravity is shifted towards the near side.
