There are now a number of standalone planets on the mod portal, but with no straightforward method to search and sort them based on downloads/popularity/etc. Most are under the Content category; some have Planet in the title, some have Moon, some have neither. Tags are a mixed bag as well depending on what it specifically adds. A new "Planet" tag would make them easier to find and evaluate.

Ditto to this suggestion, many more planet mods are popping up and there isn't a clear place for them to live.
Just looking through the "recently updated" section right now there are 9 out of 20 that are related to new surfaces.

Having a better way to search for fun new surfaces to add into the game would be much easier with a new tag.
