Scale of Fictional Worlds

I regretted making an image this large before I started making it.

Suggest other things, let's see if I can fill the chart up!
Primarily I wanted to see how big Earth looked in comparison to some Star Wars planets, Kerbal Space Program, Star Trek, and how big the TARDIS would be if it was indeed "larger than Gallifrey itself".

Inset near the title is a reference to 's Starships" chart. dirkloechel.deviantart.com/art…

Some worlds have data provided but did not have a picture, so one was scrounged from the internet by simply searching "water planet" or "rocky planet".
Others are shown and have habitable characteristics but their exact size is not explicit for one reason or another. For these worlds, I estimated using my knowledge of both the fiction's universe and real world physics. The fact that some of these worlds are given a definite number when one doesn't truly exist in its source material may bother some viewers.
