The model equations of motion of the meteor in the atmosphere due to the influence of changes in Earth's gravitational field has been formulated by the use perturbation theory. In the formulation, meteor regarded as a solid ball perfectly round, not taken into account the curvature of the earth's surface, the motion of the Earth's rotation does not affect the movement of the meteor, and the Earth's gravitational field varies with altitude. Meteor motion equation model formulated by some reviewers, ie negligible friction and constant friction. Furthermore, displayed in the form of meteor trajectories in the atmosphere due to the influence of changes in Earth's gravitational field. The depiction of the trajectory of the meteor motion equation model that has been limited to two-dimensional
