How long is the Great wall of China? Is it is real that we can view from moon ?

Answer 1

It is 3,948 miles long (2,000 miles longer than the US) and 30 feet wide. No it is impossible to view the wall from the moon is exactly 238,854 miles from the earth nothing is visible from this distance with the exception of the earths atmosphere and physical characteristic as a planet.

Answer 2

The current recorded length is 7300 KMs. Chinese Govt is going to announce the new length in 2008.

/*The Great Wall is a maximum 30 feet wide and is about the same color as the soil surrounding it. Based on the optics of resolving power (distance versus the width of the iris: a few millimetres for the human eye, metres for large telescopes) an object of reasonable contrast to its surroundings some four thousand miles in diameter (such as the Australian land mass) would be visible to the unaided eye from the moon. But the Great Wall is of course not a disc but more like a thread, and a thread a foot long would not be visible from a hundred yards away, even though a human head is. Not surprisingly, no lunar astronaunt has ever claimed he could see the Great Wall from the moon.
*/ from wikipedia

It remained like a myth wether it is visible from moon or not. Even you can't locate it from Wikimapia, Google Earth whose images are taken from nearer than moon.

Answer 3

The construction of the Great Wall began between the 7th and 8th centuries B.C. when the warring states built defensive walls to ward off enemies from the north.

During the Qin Dynasty, the separate regional walls were joint together and it stretched from east to west for about 5000 thousand kilometers and served to keep nomadic tribes out.

The Wall was further extended and strengthened in the succeeding dynasties. Especially during the Ming dynasty when the northern nomadic ethnic groups became very powerful, the Ming rulers had the Wall renovated 18 times.

As a result, not the remains from the Qin dynasty were restored, but some 1000 kilometers were constructed to a full length of 6,700 kilometers.

Yes, the Great Wall can be viewed form the moon.

Answer 4

You can't really measure how long the Great Wall is unless you take it in sections, since the wall has huge breaks in it. It's not continuous. I don't remember how much total length the wall has.

As for being able to view it from the moon, that's an old wives' tale. The Great wall isn't even as wide as a typical four-lane interstate, and you can't see one of those from space, either. This is perhaps one of the most-repeated modern myths in existence, and even found its way onto a Trivial Pursuit card in one of the older versions of the game.

Answer 5

The exact length is not known. The Great Wall was built and reconstructed over many years. Satellite photos have shown extensions in the western areas not previously known. There are also some areas with multiple walls. I was told by an astronaut that, in spite of the rumors, you cannot see the wall from the moon, but parts can been made out from the space station.

Answer 6

No

Answer 7

no it is just a joke.
