Put your solar system or planet ideas here:

I think there should be more ocean planets because KSP's planets where just a bunch of rocks.

It would be cool if we could have a binary star system some time in the future. Players would have to get used to crazy gravity and wacky time zones.1761562040959.png

Without n-body physics I wonder how a lot of the binary stuff would have to be coded in as an “exception” to the normal physics. It definitely would be cool, especially if you think long term for game mechanics. Permanent bases with electrical and and thermal management needs having to handle something like that P-type planet would be an interesting challenge.

I think some ocean planets would be a fun addition- especially if players could choose which solar system they wanted to play in. (Real life system, water system, kitten-themed system, binary system, etc)

Players could land on a mostly liquid planet and deploy a submarine to explore the watery depths. If alien life is added, players could explore and study the fishes for science. Maybe even take a few back to their homeworld.

This would be good, but I suspect the devs will leave much of it to modders; what you are saying sounds very much like a system editing mod like Kopernicus with lots of planet packs available.

Oceanic worlds could definitely be interesting. Especially with all the water tech already laid out. You could have a really “stormy” one with big waves or one with some weird density that would permit very heavy vessels to float or the opposite.

Yes! There are no hycean planets in KSP, and barely any mods adding them.

dumb planet idea: the entire thing is a giant neodynium magnet. it disrupts signals/communications on vehicles close to its surface or landed on it, and within 10m of the surface there is a motion-dampening effect and 100x gravity for any defenitely magnetic ferrous components.

best method to leave it is to add a "seperator" truss block under your lander to keep its engine and launcher stage far enough from the surface to not get stuck.

Probably my most wanted one: A Titan analogue. The most unique moon in our solar system, especially considering the atmosphere thickness against its gravity. Natural location for ISRU, given the literal seas of methane and water ice surface. Potential for life based on alternative biochemistries. Good place for both flying and submersible craft.

A Vesta analogue. We always need some asteroid belt representation, and Vesta is very interesting. It rotates quickly for an asteroid (5.342 hours), probably due to the two enormous craters on its south pole, 1 billion and 2 billion years old respectively. These craters contain a 22 kilometre tall mountain, and there are some of the longest canyons in the solar system around its equator. The best way to make rocky planets more interesting is weird geography (think the Dres canyon and the Mohole.)

A really intense magnetic field could be cool, my suggestion would be for it to be on Proxima Centauri d, as solid evidence was found for it having a magnetic field stronger than Earth's and possibly Saturn's, anywhere from 8 to 230 Gauss (earth's is 0.25 to 0.6 Gauss). I think interfering with communications would be interesting but getting magnetized to the surface might be a bit annoying.

I also think a planet with a deep sea could be great, but a non-water sea would be even better. (It'd also be easier to justify if it wasn't in the habitable zone.)
