CHINA (CBS) - A southwestern Chinese city wants to launch a fake moon into the sky by 2020.

It's actually a satellite that would reflect the sun's rays at night.

It will reportedly be eight times brighter than the real moon and could replace street lights -- saving the city more than $200 million a year.

Astronomers, though, are concerned about the increased light pollution it could cause.
