Natural satellite (Portions of atmosphere, cryosphere, hydrosphere, lithosphere)

[alanruttenberg]

All use "natural satellite" in their definitions, but natural satellite isn't defined. I've been using the terms "astronomical body" defined as: A material entity that is a natural resident space object that is a single, cohesive structure bound together by gravity and/or electromagnetism.

"Natural resident space object" is adapted from https://en.wikipedia.org/wiki/Resident_Space_Object

"Satellite" connotes either the artifact, or a moon - something in relation to a planet, so isn't as general.

Also, by the definition of Portion of Geosphere, it would seem that Portions of Hydro, Litho, Atmosphere are subclasses of Portion of Geosphere. From the definition of Portion of Hydrosphere it would seem Portion of Cryosphere is both a subclass and part of it?

Finally, along these lines, I need a term that would be something like the material in a site surrounding a material entity, on which climate can depend on. Wind speed, air temperature, water temperature around a ship would be an example of something I need to represent.

Alan's second point (re: apparent subclass relations) seems correct to me. It's an issue I was also planning to raise.
