A
There are countless myths to explain how the world came to have a moon to bring light to the night time. But now there is a plan for a man-made moon. It will give us far more light than the natural moon.
China is preparing to put a man-made moon in the sky above Chengdu by 2020. It will reflect sunlight back onto the Earth. If it succeeds, three more such objects will be sent out in 2022, according to Wu Chunfeng, a space scientist. Wu said it would be similar to how we get moonlight, but he predicted that the man-made moon would have eight times the brightness of the real one. "This is because the object will be about 500 kilometers above the Earth. That will make it a lot closer to us than the Moon, which is over 380,000 kilometers away," Wu added.
If the plan works, the man-made moon will save a lot of power. Scientists predict that Chengdu could save around 1.2 billion yuan on electricity every year if a new moon lights up 50 square kilometers of the city. And in 2022, four man-made moons can take turns to work as they
will not always be in the best position relative to the Sun. Together, they can give light to an area of up to 6,400 square kilometers on the Earth for 24 hours. That means its brightness will be seen in most areas in China, reducing the need for streetlights.
