We almost always see the same surface when we stare at the moon, the same patterns of craters and cavities, thanks to the way that the moon moves, rotating and revolving around earth So, what about the other surface of our only natural satellite? The moon is tidally locked to earth, meaning it rotates on its axis at the same speed as it orbits earth This results in the moon always showing the same face to earth, and explains the far side and dark side misconceptions. The moon orbits earth in synchronous rotation, always keeping the same face toward us Learn how humans have explored the nearside and farside of the moon with space missions and satellites.
The simple answer (and one that you've probably heard before) is that we only see one side of the moon because the moon rotates around the earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth This means that one full 'day' of the moon (meaning the length of time it takes for the moon to rotate. Over billions of years, the earth's gravity has forced the moon to spin synchronously with its orbit However, things are a bit more complicated than that Viewed from earth, the moon appears to rock slowly backwards and forwards so that we see a slightly different face throughout the lunar month There are two main reasons for this.
Physical libration refers to minor wobbles in the moon's orientation caused by the uneven gravitational pull from earth on its slightly irregular shape These motions add to the observable surface area. The first time humans actually got a glimpse of the far side of the moon was in 1959, when the soviet spacecraft luna 3 beamed back the world's first images It was a pretty big moment, because we're so used to seeing the same side of the moon, day in, day out In the latest episode of. Even though we cannot see the other side of the moon from earth, humanity has found a way to sneak a peek to whet our curiosity
The secret of the dark side of the moon is revealed, but the universe is full of other hidden places. In 1959, the soviet luna 3 probe provided the first images of this lunar hemisphere The moon's slight wobble while the moon largely keeps one face toward earth, we see slightly more than 50% of its surface over time due to libration This slight wobble allows observers to glimpse about 59% of the moon's total surface. The moon is tidally locked with earth, meaning it rotates on its axis at the same speed as it orbits earth This synchronous rotation makes us always see the same side of the moon, but we can see more than 50% of its surface due to libration.
