“…Recently there were various space missions dedicated to visiting asteroids in the Solar System [1,2,3,4,5,6]. Studying the dynamics around asteroids becomes necessary in order to run the space mission smoothly [7]. The dynamics around the asteroids can be analyzed by developing the gravitational potential model.…”

In this paper, we revisited the model of gravitational potential generated by irregular shapes. A finite straight segment model was used to investigate the motion of particles around a massive straight segment of length 2l, mass M, and uniformly rotates with angular velocity ω. We extended this model by converting it to the cylindrical coordinate and applied this model to the asteroid (338) Budrosa. We obtained the position of equilibrium points in this system. We also estimate the zero-velocity curve and determine the Poincare map and its periodic orbit around equilibrium points.
