At school, our imagination was struck by stories that only the Great Wall of China is visible from outer space. It turns out that people created a lot of impressive buildings, which can be seen from a height of hundreds of kilometers. However, from 400 km - the highest point of the ISS orbit - man-made structures are not visible without the help of optics, but if you go lower, you can see a lot of interesting things. The height of the orbit of American shuttles was about 200 km, but numerous satellites fly even lower.
All that astronauts admire, you will find in today's Top-10 man-made objects on Earth, which can be seen from space.

10. Kuibyshev Reservoir
This artificial reservoir area of 6.45 thousand km?is the world's second largest river reservoir. It is also called the Zhiguli Sea. The purpose of the reservoir is irrigation, electricity generation, fishing development and other important tasks.
9. Naska lines
Presumably, these mysterious geoglyphs were built between 400 and 650 years of our era. The lines are located in the south of Peru on the Nazca plateau. One of the hypotheses suggests that these lines are signaling and are intended for landing of alien ships. And consequently, nothing surprising and should not be that they are seen from space.
8. Lake Volta
The world's largest man-made reservoir is in Africa on the Volta River and has an area of 8.5 thousand km? .The lake occupies 3.6% of Ghana's area. More than 5.5 million people live on the shores of this reservoir.
7. Sheikh Hamad's name
An odd Arab sheikh-billionaire Hamad bin Hamdan Al Nahyan built the inscription "HAMAD" on the private island of Al-Futaisi. The height of each letter is 1 km, the length of the inscription is more than 3 km. The first 2 letters are navigable channels filled with water.
6. Peacock tail quarry
These heaps of the world's largest quarry, located on the territory of Chile, are clearly visible from space. The mine is located in the Andes at an altitude of 2840 meters, copper and molybdenum are mined here. The depth of the quarry is 900 meters, length - 4,3 km.
5. Sultan's Horse
This earth sculpture was created from coal slags mined at the mine in Kaifilli, Wales. Of course, with the ISS it can be seen only with the use of optics, but here on satellite images "Sultan" is seen very well.
4. Firefox Logo
In the fields of the American state of Oregon in 2006, a circle was created in the form of a logo of the then young Firefox browser. A picture with the logo became one of the most popular places in Google Earth. Such original advertising really helped to attract new users to the browser.
3. Great pyramids of Egypt
Giant tombs of ancient pharaohs have a height of 138 to 146 meters. Some researchers believe that, like Nazca's, the pyramids are beacons for alien aliens. Be that as it may, they are really easy to see from a near-earth orbit.
2. Artificial island Palma Jumeira
Bulk islands in Dubai are included in many ratings and tops. Palm Jumeirah - the largest among the man-made islands and one of the most expensive structures in the world. Sixteen branches of the palm island and the surrounding embankment are perfectly visible from the orbit.
1. Great Wall of China
This grandiose structure has almost 9,000 km in length, taking into account the branches. The construction of the wall began in the 4th century BC.and continued unhurriedly until 1644.The wall is really visible from the orbit with the naked eye, but only under ideal weather conditions.
