Protected Region

(an area around a body where an orbit can be stable)

Protected Region can refer to a set of possible orbits around a celestial body that are stable. For example, it may be that two orbiting planets' orbits are sufficiently separated that a planet could orbit between them. An orbit too close to one of the two would be affected by that planet and the orbit would not last. The region between sufficiently far from both planets for a lasting orbit of another planet is a protected region.
