Kop Challenge Rules

Planets must be made using an up-to-date version of Kopernicus and Kerbal Space Program. Any planets that are not updated to the current version will be disqualified.
Planets must be created for this contest. No planets released in other planet packs may be entered.
Any planets must be entered for the competition before the completion of each challenge. After the final day, submissions will be ignored.
All planets must be released to myself under an MIT license, such that the worlds can be polished and made more consistent with each other so they can be released as a community planet pack. We can discuss alternate licenses in the private messenger. All credit will be given to the creators of the planets.
Any entry containing a generic Space Engine export will be disqualified, however those which use the in-game editor may not be if it looks good in KSP.
One planet per person per challenge round.
Co-operation with other people is fine, but must be restricted to one planet per team.
The above two rules may be loosened if a challenge calls for a specific number of bodies together.
No plans, ideas, screenshots/images, or files regarding your planet may be shared until the completion of the challenge round for which it was designed.
