[WIP][1.8.1, 1.9.1, 1.10.1, 1.11.0–2, 1.12.2–5] Principia—version کاشانی, released 2024-05-08—n-Body and Extended Body Gravitation
The source code is available on GitHub under the MIT license.
Abstract
This mod aims to replace KSP's unstable physics integration with a higher-order symplectic integrator, adding n-body Newtonian gravitation in the process.

Documentation and download
Principia is not built in the same way as most other mods (most of it is native code, with a thin C# interface layer), so that compatibility issues may arise depending on the platform.
Binaries are availabl
For the new moon (lunation number 289), the new release (ابن الهيثم) is out.
A new rotating and pulsating reference frame has been added; it is in this frame that the Lagrange points are defined for the elliptic restricted three body problem.
When this frame is used as the plotting frame, the equipotentials of the centrifugal plus gravitational potential are drawn, so that the Lagrange points can be seen.
This provides valuable context when planning low-energy transfers and other
