Apsidal motion in eccentric binary systems is the rotation of the major axis in the plane of the orbit. The study of apsidal motion in binary stars with eccentric orbit is well known as an important source of information for the stellar internal structure as well as the possibility of verification of general relativity.
In this study, the apsidal motion of the eccentric eclipsing binary GG Ori ( P = 6.631 days, e = 0.22) has been analyzed using the times of minimum light taken from the literature and databases and the elements of apsidal motion have been computed. The method described by Giménez and Garcia-Pelayo (1983) has been used for the apsidal motion analysis.
