Answer Because of the proximity of the moon to the earth and the effect of the earth's gravitation on the moon, the moon has experienced tidal locking and is now in wha…t is called synchronous orbit about the earth. We always see the same side of the moon because it makes one rotation about its axis for every orbit it makes about the earth. Exactly. The curious person would follow the related links below to get more of the particulars.
in northern hemisphere the sunlit part of the moon moves from right to left and in the southern hemisphere the sunlit part of the moon moves from left to right
Relative to the Earth, the Moon makes one rotation every 27.32 days. That happens to also be the time it takes for the Moon to complete one revolution around the Earth. Theref…ore the same side of the moon is more or less always pointed toward the Earth and we only see that same side. The moon orbits around the earth once every month. It happens that the rotation of the moon on its axis is tidally locked with the earth. This means that the moon's rotational period is equal to its orbital period around the earth. For every monthly revolution around the earth, the moon has one rotation on its axis. So wherever the moon happens to be in its orbit, the moon has rotated enough so that the same face (for the most part) is toward the earth. There is an interesting phenomenon called libration (an apparent motion, not a true motion) that makes the moon appear to swing a little back and forth, and up and down. But on average, there is one rotation for every revolution. If this were not true, every part of the moon's surface would face earth at one time or another.
What is this called during these moon phases the amount of the lighted side that can be seen begins to decrease?
The phases where less of the moon is seen are called "waning", "waxing" refers to an increasing amount of visible moon.
new moon and full moon phase .
Yes. The only people who have seen the other side *first hand* are the astronauts who went up there, and I'm glad they took pictures. The moon is rotating at the same rate it …is orbiting the earth, so the same side of the moon is always facing the Earth (or at least has been for several thousand years of recorded history). Yes, pretty much so. The Moon is "tidally locked" to the Earth, so that the Moon spins once in the same time as it takes to complete one orbit. Thus, the "near side" of the Moon is always visible from Earth, and we earthlings never saw the "far side" of the Moon until the first Soviet space probes sent back pictures of the other side. The Moon's rotation is constant, but its speed in its orbit is not. So we see a tiny sliver of the Moon more than the 50% that we might expect; we get little peeks just a little way around the Moon as it follows its elliptical orbit. When men settle the Moon, most of the settlements are likely to be on the near side, where we'll be able to see the Earth. But some adventurous souls, no doubt, will prefer to settle on the far side, where the Earth will never be visible.\n. \nYou can see the moon "wobble" in the link below which shows a full cycle; the moon is slightly closer to Earth at some times than at others, so its apparent size also changes.
Yes. Because of its locked orbit, the same side of the moon always faces the Earth.
Provided your sky is clear and you know when and where to look, you can see at least some of the moon's lighted side on roughly 26 days/nights out of every 29. At the time… of the Full Moon, you see essentially all of it.
No. The amount of the Moon visible from the Earth varies, depending on the phase of the Moon. At Full Moon, you see nearly all of the Moon's illuminated side. At New Moon, y…ou see nearly none of it. At Quarter Moon, you see about half of it.
The question may mean "Why?" not "What?" That question is answered elsewhere.
What is this called during these moon phases the amount of the lighted side that can be seen begins to increase?
Because the period of the Moon's revolution around the Earth and the period of the Moon's rotation on its axis are precisely equal.
You can see the same amount of the moon during the first and last quarter, as well as during each half.
In The Moon
No, the amount seen varies with the phase of the moon.
