Radar Observations: radar observations is more general that radar astronomy. We use radar instruments on spacecraft to image the surface, and we do not refer to this as radar astronomy.

• is there another word that would be acceptable other than radar? or words that could enhance the meaning with this context? I'm thinking something like "remote sensing" "imaging radar" "planetary radar"?

Tectonics: plate tectonics is a subset of tectonics, that only really operates on Earth. Tectonics would be a better, more general concept.

• I can see adding "Tectonics" with "plate tectonics" as it's child concept. Right now "plate tectonics" is a child of "planetary structure," but I think both this and "Tectonics" would be better situated under a new "Planetary dynamics."

Volcanism: Volcanoes is not the same as volcanism. Volcanism is the more general term for volcanic processes, that don't all come from volcanoes. I would advocate replacing "Volcanoes" with "Volcanism".

• Similar to tectonics, I can see "Volcanism" as a child term of "Planetary dynamics" would that make sense?

Jovian planets: Could we simplify it to "Gas Giants"? That would cover Jovian planets in our solar system, and extrasolar systems.

• The UAT also has ""Outer planets"" which suffers from the same problem as "Inner planets" pointed out below. What about replacing "Outer planets" with "Solar system gas giants"? the UAT has a concept for "extrasolar gas giants" already.

Planetary dynamics: We should have planetary dynamics as well [as exoplanet dynamics]. There is a huge field of planetary dynamics that does not look at extrasolar objects.

• agree, likely to be added

Terrestrial planets: Could we replace "Inner planets" with "Terrestrial planets"? That is the more widely used term for the rocky bodies in the inner solar system.

• yes, this should be updated. "Solar system terrestrial planets"

Aurorae (see also #318)

• Should this concept be generalizable for other solar system planets than just Earth?

Lightning (see also #265)

• This concept should be generalizable for other solar system planets than just Earth?

Updated "Inner planets" and "Outer planets" as described above.

[katieefrey]

Planetary dynamics added as child of "Planetary science." Child concepts "volcanism" and "tectonics" as described above. For further discussion about the placement of this concept, see #335.

[katieefrey]

Instead of "Radar observations," we're going with "Remote sensing" as a "catch-all term for any planetary work using remote observations. It would include radar, but also VNIR, TIR, etc. wavelengths."

Aurorae (child of planetary magnetospheres) and Lightning (child of planetary atmospheres) added. Location might be subject to change in future releases, but I think these are good for now.

That's everything for this issue!
