Once anything collides with anything in orbit it has a slightly different trajectory. Any movement up or down will make its orbit more ellipsoidal than the original orbit. Also the atmosphere moves up and down in response to solar wind and therefore varies in both time and space. Atmospheric drag is apparently still a factor up to 600km https://www.swpc.noaa.gov/impacts/satellite-drag Debris in a crowded orbit will eventually collide, no matter how synchronized it all was initially. |

> Debris between 1 cm and 10 cm (approximately 500,000), referred to as the “lethal” population, are the most concerning as they cannot be tracked or cataloged and can cause catastrophic damage when colliding with a satellite. Objects smaller than 1 cm (approximately 135 million measuring from 1mm to 1cm, and many more smaller than 1 mm) that could disable a satellite upon impact are termed the “risk” population
