Suggestion: Optional Planet 9 addition/s
What it says on the tin. Bit of a stray from what this mod intends to add, but it's worth suggesting at least.
Planet X was recently (2016) re-proposed as a solution to the clustered, eccentric orbits of some TNOs such as Sedna, which are far more elliptical than expected, if not improbable without outside influence - The idea being that this planet 9 would've 'sheparded' their orbits' into this cluster. This hypothesis has yet to be confirmed, and does face criticism, but is also supported by many planetary scientists.
This hypothesis, formulated by Konstantin Batygin and Michael E. Brown; can be found here: https://caltech.app.box.com/s/lytrue5umoc1j0vla6puc9fz82c75t5j A more readable form of their proposal can be found on NASA's website here: https://science.nasa.gov/universe/exoplanets/planet-nine/
Some notes:
- Given it's hypothesised mass between five and ten earth masses, it could sit on the cusp of being an ice giant, or it could be a super earth with an ultra dense atmosphere.
- It is likely it would have moons, but they'd likely be similar to Neptune's minor moons. Like Neptune, it could have captured a Kuiper Belt object. (like Triton)
- Michael E. Brown also suggests the existence of Planet Y, which would be an earth-sized dwarf planet past the Kuiper Belt. I can't find too much on this so I'll have to leave it to you to do research.
- If added, this should be OPTIONAL! all of the content in this mod is (hence why it isn't recommended to have it all downloaded at once), but an emphasis should be made that this/these are hypothetical planet/s
- If possible, name-swapping between their Planet X/Y names and some Roman god/deity names.
According to the latest data in July 2025, the mass of Planet Nine is about 4.4 times that of the Earth.
Hi, sorry for the late reply, been busy these months
YES I'm interested in making Planet 9 although I'm not a big fan of believing it really exists
I accept your suggestions on Planet 9 (Planet X). I'll make separate versions of it, a mini-Neptune and an super-Earth
I'm not really interested in Planet Y though, so I'm not considering making it

Don't worry, I've been having to take breaks from KSP too due to IRL stuff. Thanks for the addition in advance, by the way!
