Earth orbits

  1. IN a relatively circular earth orbit, how far away from earth would you have to be in order to avoid collisions?

    Collisions with what?
     
  4. sorry, man made objects

    Ah. What do you know about the subject so far? What altitudes are used for the various low-Earth orbits? What altitude is used by geosynchronous satellites?
     
  6. I should have been more explicit. Circular geosynchronous orbits, 26,000 miles as i understand it, is rarified as far as man made objects. I was wondering how far above earth an object would have to be to have a high likelihood of not colliding with low earth orbit objects and above.

    To my understanding, once your out of LEO you've passed most of the debris.
