The coplanar orbit transfer problem has been an important topic in astrodynamics since the beginning of the space era. Though\r\nmany approximate solutions for power-limited orbit transfer problem have been developed, most of them rely on simplifications\r\nof the dynamics of the problem. This paper proposes a new approximation method called primer vector approximation method\r\nto solve the classic power-limited orbit transfer problem. This method makes no simplification on the dynamics, but instead\r\napproximates the optimal primer-vector function.With this method, this paper derives two approximate solutions for the powerlimited\r\norbit transfer problem. Numerical tests show the robustness and accuracy of the approximations.
