China to launch artificial moon by 2020 enough to replace streetlights

China has a plan to launch an artificial moon enough to illuminate the city of Chengdu, the capital of China's Sichuan province.

The announcement has been made in public by Wu Chunfeng, chairman of Chengdu Aerospace Science and technology Microelectronics System research Institute Co.,Ltd, during the national mass innovation and entrepreneurship activity held in the city on Oct. 10, Peoples Daily reported.

The artificial moon is expected to orbit about 500 kilometers above the earth and said to be eight times brighter than the real moon, according to state media Peoples Daily.. The said project could save more than $200 million a year in electricity cost.

The project could also be used to light up areas experiencing power outages in times of natural disasters.

The project is set to be completed in 2020 and testing of the illumination satellite had started years ago.

However, the project sparked concern from the public, as many began to worry that the lights from the artificial moon could affect animal behaviors. 

In response to the concern of the public, Kang Weimin, director of the Institute of Optics, School of Aerospace, Harbin Institute of technology,assured that the light of the satellite is similar to a dusk-like glow, so it should not affect animal's routine, reported.

The artificial moon project was first realized by a French artist - of a mirror necklace hanging above the planet that would reflect the light of the sun through the streets of Paris, the report said.
