China plans to launch a massive fake moon into space.
The southwestern Chinese city of Chengdu intends* to launch what could be the world’s largest light globe and orbit it about 500km above the Earth. That’s farther* into space than the International Space Station, which orbits about 400km above the Earth.
The project, which is set to be completed in 2020, could save more than $200 million a year in electricity costs.
Chinese government newspaper People’s Daily reported that it is “designed to complement* the moon at night”.
The fake moon’s glow is predicted to light up an area with a diameter* of 10-80km, making it eight times as bright as the real moon.
The light emitted* could be enough to completely replace street lights, researchers believe, and if it covered 50sq km, it could save $240 million in electricity costs each year.

The project was introduced to the public by Wu Chunfeng, chairman of science company Chengdu Aerospace Science and Technology Microelectronics System Research Institute Corporation Co.
Mr Wu made the announcement at a Chinese innovation* and business fair in Chengdu last week
He explained that the testing of the illumination satellite — another way of saying glowing, orbiting moon — started years ago, and now the technology has finally caught up with the idea.
Some people are worried the light could affect the daily routines of animals.
King Weimin, from Chinese University Harbin Institute of Technology, disagreed. He said the light of the satellite is similar to a dusk*-like glow, so it should not affect animals’ routines.
The cost of the project has not been announced.
A similar project was planned by Russian researchers in 1999. This idea used orbiting mirrors to light up cities in Siberia, Russia, as a cheaper alternative to electric lighting.
This project used a spacecraft called Znamya 2, which used a 25m mirror to light up a patch of land 5km wide.
The UK’s Telegraph newspaper reported that during its first orbit the Russian craft was destroyed following a collision in space and the project was abandoned.
