Artificial moon
An artificial moon is a satellite put into a planet's orbit to reflect sunlight back to that planet.
By 2022, China plans to have three artificial moons in orbit around the Earth. These will shine 8 times brighter than the natural moon. By having this as a light source, China believes it could save over a hundred million dollars a year from the cost of electricity used for streetlights.Concerns
