"Nearly 70 years after the Soviet Union launched the first satellite, there is more man-made material in space than ever before. The increasing quantity of satellites and debris in low-Earth orbit—roughly 100 to 1,200 miles above the planet—is raising concerns of collisions that could damage or destroy spacecraft and satellites. One worst-case fear is that debris could set off a chain reaction of crashes, leaving parts of low-Earth orbit unusable." https://www.wsj.com/science/space-astronomy/spacex-and-rivals-dodge-traffic-as-satellites-debris-crowd-low-earth-orbit-2a870efe #SpaceEnvironment
