Propose adding:
"Exoplanet surfaces" as child term to "Exoplanet structure"
Propose adding more general layer between "Exoplanet structure" and "Exoplanet surface characteristics" as follows:
Exoplanet astronomy
...Exoplanet structure
......Exoplanet surfaces (proposed new term)
.........Exoplanet surface characteristics
Did not propose "Exoplanet surface processes" as new child term to proposed "Exoplanet surfaces" to align with Solar System equivalent since there is not much in the literature at this time specifically on "surface processes" of exoplanets.
