Some very interesting orbits some of that junk got into. The story on those would be nice.
Some of the early launches had some strange orbits
In fact one of the first US satellite launches was the Vanguard 1, March of 1958, it is still up there along with 2 other Vanguards launched later.
Making Vanguard 1 the longest orbiting artificial satellite, it looks to stay up there for close to another 200 years. It stopped operating completely in 1964.
