The Great Wall of China is visible from the moon.

The statement that "the Great Wall of China is visible from the moon" is false. This misconception originated from a 1932 book that mentioned the wall's visibility from the moon, but it is not supported by scientific evidence. The Great Wall of China is not visible to the naked eye from the moon due to various factors. It is only a few meters wide, and the moon is 384,400 kilometers away. Other man-made structures, such as highways and airports, are not visible from space either, let alone from the moon.
