N-body Model in Astrophysics

An L3 physics internship result comparing real and simulated trajectories.

Three-body simulation: Earth, Moon, and satellite trajectories
Three-body simulation: Earth, Moon, and satellite trajectories

Result from my L3 physics internship on celestial mechanics. We studied the classical N-body model in astrophysics and plotted the trajectories of the Moon and an Earth-orbiting satellite relative to the Earth. The black dot represents the Earth, the blue curve corresponds to the actual satellite trajectory, and the red curve represents the actual Moon trajectory (real data obtained from NASA). Using the 3-body model, we simulated the green trajectory for the satellite and the yellow trajectory for the Moon.
