Sun-Earth-Moon-Spacecraft four-body simulation using MATLAB - unexpected results [closed]
I'm trying to simulate this four-body system by directly integrating the system of equations
$$\ddot{\textbf{x}} = \sum_{i=1\:i\neq k}^4 G\frac{m_i}{|\textbf{x}_i-\textbf{x}_k|^3}(\textbf{x}_i-\textbf{...

How to calculate the new position at time $t$ of celestial bodies with variable acceleration?
Intro
For an $N$-body simulation of celestial bodies I need to calculate
on the one hand the accelerations of the celestial bodies based on the received gravitational forces [done]
and on the other ...
