There are plenty of myths(神话) 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. People believe that the plan will give us much more light than the natural moon.
China is preparing to put a man-made moon in the sky above Chengdu by the end of 2021. 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 much closer to us than the moon which is over 380, 000 kilometers away, Wu added.
lf the plan works, the man-made moon will save a lot of power. Scientists said that Chengdu could save around 1,200,000,000 yuan in electricity every year if a new moon lit up the city. And in 2022 , four man-made moons can take turns reflecting sunlight. Together, they can give light to most areas in China to reduce the need for streetlights.
