Artificial moon will illuminate Chinese cities.

Wu Chunfend, chairman of the Chengdu Institute of Microelectronics and Space Technology, revealed the plan at a city event. According to him, the artificial moon could be controlled to illuminate an area with a diameter of 10 to 80 kilometers, saving the city up to 1.2 billion yuan (approximately $178 million) in electricity costs. It remains unclear whether the project will be successful.

The artificial moon project has faced some criticism for causing light pollution and affecting astronomical observations. However, Director Kang Weimin of the Institute of Optics stated that the satellite will only emit a faint glow, similar to twilight.

This isn't the first time humans have attempted to send a light-reflecting object into space, but most similar plans have failed.
