China is in the process of creating an "artificial moon" that would be bright enough to replace the streetlights in the south-western city of Chengdu by 2020. Chinese scientists plan to send three artificial moons into space in the next four years, and the moons - made from reflective material like a mirror - are expected to orbit at 500 kilometres above the Earth and light up an area with a diameter of 10 to 80 kilometres. The artificial moon will have a reflective coating that can deflect sunlight back to Earth, similar to how the moon shines.
