By some time you mean some hundreds of millions of years, it’s not plastic in earth/ocean or uranium which degrades relatively quickly in comparison, there is not much of degradation in orbit.

At altitudes of 500 miles (800 km), the time for orbital decay is often measured in decades. Above 620 miles (1,000 km), orbital debris normally will continue circling Earth for a century or more.
