In this paper, the basic classification of asteroids and the history and current situation of
asteroid exploration are introduced. Furthermore, some recent research progress on the …

One of the most accurate models currently used to represent the gravity field of irregular
bodies is the polyhedral approach. In this model, the mass of the body is assumed to be …

In order to obtain the gravitational field of a general finite body inside its Brillouin sphere, we
developed a new method to compute the field accurately. First, the body is assumed to …

We study the motion and equilibria of the grains on the surface of the irregular celestial body
(hereafter called irregular bodies). Motions for the grains on the smooth and unsmooth …

Radar observations show that (16) Psyche is one of the largest and most massive asteroids
of the M-class located in the main belt, with a diameter of approximately 230 km. This fact …

We investigate the multiple bifurcations in periodic orbit families in the potential field of a
highly irregular-shaped celestial body. Topological cases of periodic orbits and four kinds of …

ABSTRACT The New Horizons space probe led the first close flyby of one of the most
primordial and distant objects left over from the formation of the Solar system, the contact …

The motion of a massless particle in the gravity of a binary asteroid system, referred as the
restricted full three-body problem (RF3BP), is fundamental, not only for the evolution of the …

Research on the stabilities of periodic orbits is useful for selection of parking orbits in
asteroid and comet missions. In this paper, retrograde near-circular periodic orbits near …

We investigate the equilibrium points and orbits around asteroid 1333 Cevenola by
considering the full gravitational potential caused by the 3D irregular shape. The …
