21. The radius of the photon sphere, which is also the lower bound for any stable orbit , is: 22. I asked him to consider a satellite in stable orbit that suddenly breaks into two unequal parts. 23. :: Maybe I'm misunderstanding you, but objects do not naturally " move towards " a stable orbit . 24. A fourth satellite failed to achieve a stable orbit due to a problem with the third stage. 25. Neptune trojans are in a 1 : 1 mean-motion resonance with Neptune and often have very stable orbits . 26. All of the putative stable orbits are occupied by planets except one, which corresponds to the asteroid belt. 27. Orbital resonance from major orbiting bodies creates regions around the Sun that are free of long-term stable orbits . 28. :Correct my if I'm wrong, but in order to maintain a stable orbit , distance is inversely proportional to velocity. 29. Should we allow their orbits to collapse, or increase their velocities or masses to create new stable orbits for them? 30. However, the uncertainty of the orbital parameters makes it equally uncertain exactly where stable orbits would be in this system.
