Abstract
In this paper, the model of the restricted four body problem with solar radiation pressure is formulated. The model was applied on the (Sun-Earth-Moon-Spacecraft) system. The equations of motion of spacecraft under the gravitational forces of sun, earth and moon with radiation pressure for the sun. The liberation points for the system was determined with vary values of solar radiation pressure. The relations between values of solar radiation and values of collinear liberation points (L1, L2, L3) are plotted. Zero velocity curves plotted for the Sun-Earth-Moon system with different values of solar radiation.
