Can you really see the Great Wall of China from space?

Great wallOne popular space-based myth is that you can see the Great Wall of China from space. That’s not true. You can’t easily see the Great Wall from low Earth orbit with the unaided eye. And certainly, the astronauts couldn’t see it from the Moon, even though that myth has been widely circulated.

What human-made structures are then visible from space? Space Station astronauts have reported that the ancient pyramids at Giza are relatively easy to see, but most visible are the roads or long bridges across straits. Of course, at night cities can be visible from space because of the light they produce. The same astronauts confirmed you can’t see the Great Wall of China from the Moon. In fact, all you can see if you looking from the Moon is the white and blue marble of Earth.
