The prime objective of this work is to numerically investigate the stability of retrograde orbits/trajectories around Jupiter and the smaller of the two primaries in binary stellar system RW-Monocerotis in the presence of radiation. The trajectory is termed to be stable if it remains around the smaller mass for at least few hundred binary period. We have studied the stability region of retrograde motion of particle in Sun-Jupiter and RW-Monocerotis system both in the presence and absence of radiation. We found that in case of a circular binary orbit, the third order resonance provides the answer for reduction of stability region.
