Congrats. I am heading in the direction of EA after 120kly trip to BP and haven't found a suitable candidate the entire run, a few just over 18k in radius but not worthy of the list.
I wonder what will happen with the list if/when ED open up new types of landable planets, the journal won't be updated backwards so I guess we will just have to go through our possible large bodies manually and check then against a database like EDSM to see of they have become landable. If they open up a certain type, say icy atmospheric bodies or the hell planets I am sure the Observatory can be set to pull the large examples of those out and then we just need to check them out ourselves.
