WebIn low Earth orbit (below 600 km or 370 miles), the little atmosphere that is there will, over weeks, months, and years, drag the space debris low enough to reenter. Between 600 km and 1000 km (620 mi) it may take tens to hundreds of years for the debris to reenter. WebOf course, the sun's pull slows it down again in the process, at which point the earth turns back and starts the cycle all over again. The amazing thing is that the two effects of speeding up plus stronger gravitational attraction perfectly balance, so that the earth stays in its orbit, the same way a marble stays at the bottom of the bowl ...
