"China is to launch a fake "moon" into space that it hopes will illuminate one of
the country's biggest cities.

Officials in Chengdu, a city of 14 million people in China's southwestern
province of Sichuan, announced plans to place a satellite in orbit by 2020
capable of reflecting sunlight onto its streets at night, claiming it will be
bright enough to entirely replace street lights.

The satellite would use a reflective coating to direct light to illuminate an
area on earth of up to 50 square miles, according to Wu Chunfeng, chairman of the
city’s Aerospace Science and Technology Microelectronics System Research
Institute."

Will people there be able to see the stars at night if this is done?

Of course not. I can't see the stars at night because of the street
lights. Only the moon, maybe a bright planet.

How much heat will come with the light?

I can see a thousand or so of the brightest stars. But nothing like what
I could see 50 years ago.
