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. I've been compiling this since the first starbound thread and got everything looking nice and sorted. Hopefully someone who visits all of them or the original co-ordinate posters can fill in the holes.

Sectors/Planets have been organized. 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 above them.
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.

Finally fully sorted by Sector, Threat Level and Notable features.  Layout still a work in progress
