In how many days does the moon rotates ? And Why do we see always the same face of the moon from earth?

Answer 1

Basically it takes 27 and 1/3 days to revolve around the earth, which is called a "siderial month". The reason we always see the same side of the moon is because it both rotates and revolves at the same rate. Think of a big circle around the earth. As the moon revolves in that circle, it's rotating, but pretty slowly, so that even though it's riding a curve around our planet, we always see the same side. (It's kind of hard to explain without showing you.)

Answer 2

I think the rotational period is 28 days but I can't remember for sure.

The Moon always shows us the same face because Earth's gravity has slowed down the Moon's rotational speed. The Moon takes as much time to rotate once on its axis as it takes to complete one orbit of Earth. (Both are about 27.3 Earth days.) In other words, the Moon rotates enough each day to compensate for the angle it sweeps out in its orbit around Earth.

Gravitational forces between Earth and the Moon drain the pair of their rotational energy. We see the effect of the Moon in the ocean tides. Likewise, Earth's gravity creates a detectable bulge -- a 60-foot land tide -- on the Moon. Eons from now, the same sides of Earth and Moon may forever face each other, as if dancing hand in hand, though the Sun may balloon into a red giant, destroying Earth and the Moon, before this happens.

Answer 3

The Moon rotates around Earth in aproximately 28 days and every moon phase we see on the sky, represents a 7 day cycle. We always see the same face of the Moon because its rotation around its axis coincides with the rotation(revolution) around Earth.

Answer 4

Well it seems half of the answer to this 2 part question has been answered. But How still remains. By definition, a rotation is defined as one complete turn so that one point faces all 360 degrees of a circle in a given time. Stand still and just turn your body so you face all 360 degrees of a circle. You have rotated. Now place a chair in the middle of the floor. Walk around in a circle around the chair. Say you go counter-clockwise. Your left arm always faces the chair but you face all 360 degrees of a circle. You have rotated in the same time you revolved around the chair. This is how the moon goes around the earth.

Answer 5

The moon does not rotate. It stays in the same position according to the Earth's gravitational pull. That is what causes the tides to neap and ebb. Only the Earth rotates. The moon is just hanging on for dear life. That is why we always see the same side of the moon.

Answer 6

From Wikipedia:

The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned toward Earth at all times (there is a small variation, called libration). The side of the Moon that faces Earth is called the near side, and the opposite side is called the far side. The far side is also sometimes called the "dark side", which means "unknown and hidden", and not "lacking light" as might seem to be implied by the name; in fact, the far side receives (on average) as much sunlight as the near side, but at opposite times.

Answer 7

The moon rotates around the earth and around it self every 28.x days - that is the reason we see only one side of the moon.

Answer 8

The moon shall rotate, if it does, until it stops. And who can count the days? I have heard explanations as to why we always see the same side, although they to me do not make much sense. I should think what is not seen on the other side might be more interesting to consider.

Answer 9

here the moon rotates with same speed as earth rotates about its axis so we can only able to see one side of it .

Answer 10

in a month it rotates once, we do see different faces, the phases of the moon changes too, the moon is covered in a different way each night
