It is an adjective that does not support RAE. It would derive from the latin orbit orbitae: footprint that leaves a wagon wheel and this, in turn, from orbis orbis: wheel, circle with the prefix supra - that means " " above, " up " It would be what is above or outside of the orbit that is the path that describes a physical body in its motion around another more mass under the gravitational force. The SAR supports intraorbital to it would be the antonym.
