دراسة تحليلية لحركة القمر في ظل عزم الدوران الخارجي للأرض و الشمس

Abstract EN

The moon is one of the closest celestial bodies to the earth and to understand its movement accuratelywe need to solve the equation of the movement of the three objects system (Earth - Moon- Sun) Celestial mechanics program was used to obtain the orbital and orientation elements of themoon for the year 2015 and the next hundred years, this program depends on numerical integrationsin solving Equation of motion of the three objects1 After mapping the results using the Matlab2010program, it was observed that the change in the orbital elements was most likely periodically1 Also, the orientation characteristics and the Euler angles of the moon were studied1 In addition, the physicaland optical liberation was calculated for the next hundred years1
