Abstract: Small celestial body exploration is one of the key areas of deep space exploration in the future. The orbital dynamics
and control problem near small celestial bodies is crucial in such explorations, and urgent to be treated. This problem
involves the modeling of dynamics environment around an irregular-shaped small celestial body, and the orbital dynamics
mechanism near the small celestial body. In this paper, we survey the gravitational field modeling of irregular-shaped
small celestial body, natural orbital dynamics and control, and controlled orbital dynamics near small celestial body. We
introduce state-of-the-art and trends for the development of orbital dynamics and control near small celestial bodies. The
challenges and difficulties encountered are analyzed. Finally, we discuss the prospects for the development direction and
key issues of orbital dynamics and control for Chinese future mission for exploring small celestial bodies. 

Keywords: small body exploration, dynamics and control, gravitational field of irregular-shaped body, natural orbital dynamics, controlled orbital dynamics
