ゴミがあるのはゴミ屋敷ばかりか
海のプラスチックばかりではに。
衛星の周回軌道の周りはゴミだらけ。
The United States and private companies like LeoLabs track tens of thousands of pieces of space debris, including operational and non-operational satellites, rocket stages and unknown objects. But there are many more pieces too small to see. NASA estimates that there are roughly 500,000 objects between 1 and 10 centimeters in diameter orbiting Earth, and that there are more than 100 million particles larger than 1 millimeter. (The agency said that as of January last year, the amount of material in orbit was more than 9,000 metric tons.)
