I'm just compiling the dumps and planet screenshots that /vg/ has been posting. I haven't been to these planets and only know as much as people post about. Hopefully someone who visits them or the original co-ordinate posters can fill in the holes.

Co-ords with no sector and/or no notables listed are at the end.  They may be interesting to visit, but I don't know what they have. Co-ords that are notable with no useful information are above them.  If you test these entries, please report back with results so I can sort them better.
There may be sub-planets listed, please look for roman numerals or letters after the main planet to tell.  If that fails, try to match up biome and threat level.

Sorted by Sector, Threat Level and Notable features.  Layout still a work in progress.

Chests on ground seem to be randomized.  Still worth checking various labs/installations within.

Usefulness key posted by the princess (with formatting):

USMC prison              - prisoners can drop top tier weapons
USMC camp                - soldiers can drop top tier weapons, shield robots can drop guns
Avian Merchant Ship      - sells gun, also floats
floran village           - chests might hold plat bars or diamond
glich village            - chests might hold plat bars
glitch castle            - black knights and king can drop high tier stuff but only like 3 spawns per castle and rest is trash
apex research facility   - medium tier weapons
avian tower              - medium tier weapons
avian sacrificial temple - medium tier weapons
avian mausoleum          - low to medium tier weapons
apex town                - nothing useful unless if you kill guards
avian town               - same as apex
