Principia VS vplanet

Principia is extremely impressive, they document all their math here: https://github.com/mockingbirdnest/Principia/tree/master/doc...

One interesting detail is that the source code makes extensive use of non-ASCII identifiers, for mathematical symbols and for the names of mathematicians. One of the two primary contributors is also an active contributor to Unicode

KSP2 is still patched conics. Also here's a free n-body mod made by modders, https://github.com/mockingbirdnest/Principia

Principia - 𝑛-Body and Extended Body Gravitation for Kerbal Space Program

But one should just be aware that KSP simplifies by only tracking the strongest source of gravity. This turns all orbits into actual ellipses. But there is a mod called Principia that replaces it with the proper thing, thus allowing for very chaotic (but cool) flight paths using less thrust.

Principia has n-body

Install Principia and Real Solar System, then try again :P

Theres a mod that changes that to N-body simulation, it's called Principia

I'd suggest looking at their readme: https://github.com/mockingbirdnest/Principia

Hello!! I'm an 11th grade AP Research student and I need help running exoplanet simulations. All of the simulations lead me to GitHub repositories (which I don't know how to use) and the installation guides are confusing. I'm currently looking at VPLanet (link to GitHub repository | link to installation guide), as well as vplot, PandExo, and Exo-Transmit. If there are any other options for running models of simulations, please let me know! My research is studying hycean exoplanets and relating them to future exoplanet characterization space missions, and I want to simulate a planet's conditions as well as instrumentation.

Also, I can't believe I haven't come across VPLanet before. I will certainly be experimenting with that, especially the binary module to calculate the orbital evolution of a circumbinary planet.
