Abstract
This study concerns in addressing the lifetime and reentry of the space debris in LEO which extends from 200 to 1200 km. In this study the new Computer programs are designed to simulate orbit dynamics of space debris lifetime and reentry under atmospheric drag force by using Runge-Kutta Method to solve the differential equations of drag force and this model was adapted with the Drag Thermosphere Model (DTM78, 94), the Aluminum 2024 space debris in certain size (1-10 cm) were used in this study, which is frequently employed in the structure of spacecraft and aerospace designs. The selected atmospheric model for this investigation is the drag thermospheric models DTM78 and DTM94, because of this dependence on solar and geomagnetic activities. It has been found that the lifetime of the space debris increases with increasing perigee altitudes. It has been found that the elliptical shape of the debris orbit would change gradually into a circular shape, then its kinetic energy would be transformed into heat and hence debris destroy in the dense atmosphere.

A computer program has been developed in this work to simulate the lifetime of space debris in orbit under the influence of atmosphere drag force
This work focuses on simulation of orbital dynamics of space debris of size range (1and 10 cm) of aluminum type and their reentry dynamics from the apogee-perigee altitudes 1200 to 200 km
Summary
Johannes Kepler (1571-1630), studied the mass of observational data on the planet’s positions collected by Tycho Brahe (15461601), formulated the three laws of planetary motion forever associated with his name. They know by Kepler’s laws which are, a description of a special solution to the gravitational problem of n bodies [1]. Newton evolved the law of gravitation between two particles as a result of his study of astronomy. His law of gravitation may be written as, F
