What do you mean by mistaking street lamps for the moon?

As night falls, a bright moon rises into space. In the night sky, we can see the bright moon, but the light emitted is relatively weak. Therefore, when we walk at night, we need external forces to see the surrounding situation clearly. Nowadays, there are street lamps in the streets and lanes, which are also very bright at night. Of course, there are also some remote areas where the economic conditions are not up to standard and no street lamps are installed. In this case, it is relatively dangerous to walk at night. Therefore, the term artificial moon has also entered people's lives.

to say "artificial moon", most people probably don't have this concept. In fact, this idea comes from a French artist. For an artist, there may be many wonderful ideas. Of course, he also has a bold idea, that is, hanging a mirror in the night sky on the earth, which can reflect sunlight and illuminate the whole earth. Although this idea is very romantic, it is also opposed by many scientists. Imagine if the whole earth is in.

It is reported that after the launch of the moon, the moon with two people will also be launched before 222. Instead of the moon, the streets will not need street lamps, which also attracts the attention of many peripheral media. Most netizens think this is impossible, and some scientists think it is feasible in theory. Because if the artificial moon wants to keep the mirror in the sky forever, it needs to be placed in the earth's geostationary orbit, which is 36 kilometers away from the earth. Such a distance also requires the satellite's pointing to be extremely accurate.
