What is the only man-made structure that can be seen from space?

Answer by  newgeneration (699)

Many people believe the Great Wall of China is the only man-made structure visible from space, but this is not true. Highways, roads, and canals are visible when the orbit is low enough, and Gemini V astronauts were able to see NASA's Launch Complex 39 in Cape Canaveral.

The Great Wall of China can be seen from outer space, and is considered the only man-made structure that is visible. However, in all technicality, light itself is a man-made structure visible from space, as light bulbs are man-made and emit visible light that's much more noticeable than any other structure at night.
