"Cislunar" for arbitrary planetary systems?
It appears the term cislunar specifically refers to the space between Earth and the Moon's orbit.
Is there a generic term to describe the space between any planet and the orbits of its natural satellites, or between any body and its satellites? For example, one that could equally describe the space between Mars and Deimos (thus including Phobos' orbit), or the space within the Jovian system, or indeed the Earth/Moon system?
Or can cislunar be used in this way? I tried looking for it but it doesn't seem to appear much in other contexts.
Solution 1:
Cislunar is coined from Luna (Latin for Moon). So it only refers to our moon. However if you were to be on Mars and would refer to the space between Deimos and Mars, you could very well say “cisdeimian” space.
The same could be applied to other moons that have a name. As of now this is still science-fiction, so you are not limited with accepted terminology.
