It takes 27.3 days for the Moon to complete one orbit around the Earth and one rotation around its axis. This implies that, despite the fact that the Moon is spinning, one of its faces is constantly towards us. This is referred to as “synchronous rotation,” and it explains why we can only ever view the Moon’s nearside when we are close to it.

Why does the Earth always see the same side of the Moon?
“The moon maintains the same face towards the Earth because its rate of spin is tidally locked, which means that it is synced with its rate of rotation.” (Source: wikipedia) (the time needed to complete one orbit). In other words, the moon spins precisely once throughout each of its orbital movements around the Earth.
Do we all see the same side of the Moon?
Yes, the Moon’s phases are visible to everyone at the same time. People living north and south of the equator, on the other hand, observe the Moon’s present phase from somewhat different perspectives. Traveling to the opposite hemisphere, you’d discover that the Moon is in the same phase as it is here at home, but it would seem upside down compared to what you’re used to!
Why do we never see the backside of the Moon?
According to John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter mission, we can’t view the far side of the moon because “the moon is tidally locked to the Earth.” The shape of the moon is critical in keeping it in sync with the Earth’s rotation. Scientists think that the moon used to have its own rotation at one point in time.
What does the fact that we always see the same face of the Moon tells us about?
According to the fact that we view the same face of the Moon on a consistent basis, the Moon’s rotation period is equal to its orbital period.
Does moon rotate around Earth?
Every 27.322 days, the moon completes one complete circle around the Earth. As a result, the moon seems to be almost perfectly stationary to watchers on Earth, despite the fact that it appears to be rotating to spectators on Earth. This is referred to as synchronous rotation by scientists. The near side of the moon is the side of the moon that is permanently visible from Earth.
Who is the last human stepped on the Moon?
Cernan made history by becoming the eleventh person to walk on the Moon during the Apollo 17 mission. With his return to the Apollo Lunar Module following Harrison Schmitt on their third and last lunar trip, he became the last man to walk on the Moon until 2021.
Have we explored the dark side of the Moon?
When the Apollo 8 astronauts orbited the Moon in 1968, they were the first humans to glimpse the Moon’s far side up close and personal. Until the Chang’e 4 spacecraft conducted the first soft landing on the far side of the Moon on January 3, 2019, all soft landings, whether by humans or by spacecraft, had taken place on the near side of the Moon.
What did China find on the backside of the Moon?
On the far side of the moon, China’s ground-breaking lunar rover discovered roughly 40 feet of dust, marking a first for the country. Chinese spacecraft Chang’e 4 touched down on the moon’s far side in January 2019, becoming the first country ever to accomplish this feat.
When did we finally see the moon’s far side?
A number of missions by NASA and other space organizations have provided us with more information about the Moon’s far side since 1959. A historic circumlunar trip by the crew of Apollo 8 in December 1968 provided the first human sighting of the Moon’s far side since its discovery by the ancient Greeks. NASA’s Apollo 8 spacecraft captured this image of rough terrain on the moon’s far side.
Why is the moon always facing us?
During its orbit around the Earth, our lunar neighbor revolves. It’s only that the length of time it takes the moon to complete a complete rotation on its axis is the same amount of time it takes our planet to complete a complete rotation on its axis – around 27 days. As a result, the same hemisphere of the moon constantly faces the Earth.
