Ksp Planet Packs That Don't Change the Stock System

[Great Liao]

Hey everyone,

I hope you are doing well.

So, I've been searching for a mod to enhance the stock system, and add more planets without changing the stock system much, apart from visuals and other non-orbit changing stuff. I've been doing some digging and I found a mod called OPM. This mod seems really good, and I am going to download it, but along with it I feel that my playthrough would be cool with some exotic planets, like a water world or a carbon world. Are there any mods that add things like this?\

Thank you for helping out.

Sincerely,

Great Liao

QuackPack adds some planets close to the sun. Grannus Expansion Pack adds a new star system.
