Despite the popular belief, the Great Wall of China cannot be seen with the naked eye from space. It is only visible in certain low Earth orbit trajectories under ideal weather conditions.
The Great Wall of China is one of the most iconic structures in the world, but it is not as visible as many people believe. The wall is made of earth and stone, which are similar in color to the surrounding landscape. This makes it difficult to see from a distance, even with binoculars or a telescope.
In addition, the wall is often obscured by clouds and haze. This makes it even more difficult to see from space.
The only time that the Great Wall of China is visible from space is when the conditions are perfect. The sky must be clear, and the sun must be shining brightly. Even then, the wall is only visible to astronauts and other people who are in low Earth orbit.
So, the next time you see a picture of the Great Wall of China from space, remember that it is not a true representation of what the wall looks like. The wall is much less visible in real life.
