Discussion Overview

The discussion revolves around determining the optimal distance from Earth for an orbit that minimizes the risk of collisions with man-made objects, particularly focusing on low Earth orbit (LEO) and geosynchronous orbits.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the necessary distance from Earth to avoid collisions in a circular orbit.
  • Another participant seeks clarification on what types of collisions are being considered, specifically asking about man-made objects.
  • A participant mentions that geosynchronous orbits are at approximately 26,000 miles and suggests that this altitude is relatively free of man-made debris.
  • It is proposed that once above low Earth orbit, the likelihood of encountering debris decreases significantly.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding the altitudes of different orbits and the associated risks of collision, indicating that there is no consensus on the optimal distance for collision-free orbits.

Contextual Notes

Participants reference specific altitudes for geosynchronous satellites and low Earth orbits but do not provide detailed definitions or parameters for what constitutes a "collision-free" orbit.

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

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?
 
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.
