Implication

Randomized trial simulates orbital trajectories in a two-body system, highlighting the importance of symplectic integrators.

Key Points

This research examines the effectiveness of different integrators in conserving geometric properties in a two-body Newtonian system.
Simulated the Earth-Sun system for 100 orbital periods using four integrators: Explicit Euler, Semi-implicit Euler, Leapfrog, and Runge-Kutta 4.
Tracked conserved quantities such as angular momentum and mechanical energy errors.
Analyzed trajectories and phase-space portraits of the system.
Explicit Euler exhibited monotonic energy increase and outward spiraling trajectories.
Runge-Kutta 4 showed energy drift and angular momentum growth despite being fourth-order accurate.
Symplectic integrators maintained energy bounds and conserved angular momentum with high precision.
