Metadata-fields for distances like moon, sun and so on

[sinus]

Does anyone happen to know in which metadata field (or fields) to enter distances of planets, moons, stars and celestial objects (ISS)?
I honestly haven't done any research, maybe there are no fields for that, I don't know.

But who knows, maybe someone knows more?

Googling for

celestial objects XMP metadata

should provide some pointers.

Thanks, Mario!
