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.
