A study of the evolution of the periodic and the quasi-periodic orbits near the Lagrangian point L2, which is located to the right of the smaller primary on the line joining the primaries and whose distance from the more massive primary is greater than the distance between the primaries, in the framework of restricted three-body problem for the Sun-Jupiter, Earth-Moon (relatively large mass ratio) and Saturn-Titan (relatively small mass ratio) systems is made. Two families of periodic orbits around the smaller primary are identified using the Poincaré surface of section method - family I (initially elliptical, gradually becomes egg-shaped with the increase in the Jacobi constant C and elongated towards the more massive primary) and family II (initially egg-shaped orbits elongated towards L2 and gradually becomes elliptical with the increase in C). The family I in the Sun-Jupiter and Saturn-Titan systems contains two separatrix caused by third-order and fourth-order resonances, while the Earth-Moon system has only one separatrix which is caused by third-order resonances. Also in the Sun-Jupiter and the Saturn-Titan systems, family I merge with family II, around Jacobian constant 3.0393 and 3.0163, respectively, while in the Earth-Moon system, family II evolves separately from two different branches. The two branches merge at C = 3.184515. In the Earth-Moon system, the family II contains a separatrix due to third-order resonances which is absent in the other two systems.
