- The overwelming majority of the debris is in low orbits (under 500km or so.)
- The rest is sufficiently defuse that there is little hazard of
- collisions (except within geostationary orbits, but debris is fairly
- quickly perturbed out of these orbits.)

- They are, after all, in orbit. It's kind of pointless to say they have
- orbital velocity...

-
- No, such collisions _may_ create enough secondary debris to _interefer_
- with future orbital operations.
