Solar system is filled with many celestial bodies like planets, meteors, asteroids etc. Most of these bodies are rotating around the Sun. The study of orbital motions of the celestial bodies is important for astronomical point of view. In this paper the orbital motion of Earth is being simulated by using Keplar’s Model of orbital Motion and Newton’s Laws of motions. The simulation is achieved by using numerical method (Euler Cromer Method) and MATLAB software. Results show that varying time step in years and initial velocities of Earth motion, the Earth is getting unstable from its orbital motion.
