Hello, in order to standardize the display and search for content that adds planets, moons and other celestial bodies to the game, I'm making a big proposal on github.
Since your project is unfortunately not present on Github, I am obliged to make the request here and let you do the work (rather than simply make a PR that you could have validated).

Also, my modification is simple and consists of two characters.

‘○🌐’
- The first in-game in the mod selection menu.
- The second will be displayed on Mods.factorio.
So if you'd like to modify the following files, that would be great.

• ./info.json ‘description’:○🌐<description txt>’
• ./locale/en/locale.cfg (or base or anyname)
  [mod-name]
  title=○🌐<title>
  [mod-description]
  description=○🌐

and idem for each translation file in your mod (if the line doesn't exist, add the English one)

ps: my native language is not english, please pay no heed to the tone used which may sometimes seem inapropiate, i wish you much courage and perseverance for your project, an excellent day to you. <3
