The crowded orbit also threatens the Earth's magnetic field - Space and Astronomy. On average 23 satellites per day re-enter the atmosphere, disintegrating, and then being replaced.
This is over 26 thousand kilograms of material that passes through the layers around the Earth every day, a mass 150 million times greater than the Van Allen belt. This means that the mega-constellations of satellites are creating their own region of charged plasma characterized by a mass much greater than that of the VanAllen belt or any other zone within the magnetic field.
