Artificial moon

An artificial moon is a satellite put into a planet's orbit to reflect sunlight back to that planet.

For the electric light used to simulate moonlight, see moonlight tower.

By 2022, China plans to have three artificial moons in orbit around the Earth.[1] [2] These will shine 8 times brighter than the natural moon.[3] 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

There are some concerns about how the absence of a normal day and night cycle will effect the minds and bodies of humans and animals.[4]
