Solar System Simulator with 3D visualisation written in Java and JavaFX. Positions and velocities of more than 50 solar system bodies are continuously updated using either Newton mechanics or General Relativity. Initial positions and velocities are obtained from Nasa JPL's ephemerides. The journeys of 12 spacecraft are simulated and visualised.

In this code I have solved with three specific methods the N bodies problem with some examples. In fact, I have used the Euler explicit, Runge Kutta 2 and 4 methods . For the examples, I took the data from NASA Database to illustrate the problem. As a result, you will able, with this code, to can plot the Solar system, the trajectory of Voyager …
