Claims checked

The Great Wall of China is visible from the Moon with the naked eye.

Incorrect95%
From the Moon (about 384,400 km away) human visual acuity and the Wall's width and coloration make it indistinguishable to the unaided eye; astronauts and optics experts report it is not visible without magnification.
