In this paper, we consider the motion of a particle under the gravitational field of a massive straight segment. This model is used as an approximation to the gravitational field of irregular shaped bodies, such as asteroids, comet nuclei and planets's moons. For this potential, we find several families of periodic orbits and bifurcations. 
Periodic Orbits Associated with the Libration Points of the Massive Rotating Straight Segment
Numerical results for the families of periodic orbits that emanate from the five libration points of massive straight segment, and for some secondary bifurcating families are given.
Equilibria and Stability Around a Straight Rotating Segment with a Parabolic Profile of Mass Density
In a previous work, we established the closet form of the potential generated by a massive inhomogeneous straight segment. We studied the dynamical behavior in the field of this segment at rest. Now,
We calculate the Newtonian gravitational potential and field of a cubic, homogeneous asteroid and we a pply it to the orbit of possible satellites. Large astronom ical objects such as stars or
An efficient method for searching periodic orbits in Earth observation missions
Frozen orbits are required for Earth observational missions, where the trace is repeated on the surface after a certain number of revolutions. The design of those missions is facilitated with the
Periodic orbits in the gravity field of a fixed homogeneous cube
In the current study, the existence of periodic orbits around a fixed homogeneous cube is investigated, and the results have powerful implications for examining periodic orbits around non-spherical
Periodic attitudes and bifurcations of a rigid spacecraft in the second degree and order gravity field of a uniformly rotating asteroid
In this work, periodic attitudes and bifurcations of periodic families are investigated for a rigid spacecraft moving on a stationary orbit around a uniformly rotating asteroid. Under the second
Periodic motion near the surface of asteroids
We are interested in the periodic motion and bifurcations near the surface of an asteroid. The gravity field of an irregular asteroid and the equation of motion of a particle near the surface of an
The motion of a particle about a non-rotating 2nd degree and order-gravity field is investigated. Averaging conditions are applied to the particle motion and a qualitative analysis which reveals the
Orbital Mechanics near a Rotating Asteroid
Abstract.This study investigates the different novel forms of the dynamical equations of a particle orbiting a rotating asteroid and the effective potential, the Jacobi integral, etc. on different


The gravitational potential of a homogeneous polyhedron or don't cut corners
A polyhedron can model irregularly shaped objects such as asteroids, comet nuclei, and small planetary satellites. With minor effort, such a model can incorporate important surface features such as
The critical inclination in artificial satellite theory
Certain it is that the critical inclination in the main problem of artificial satellite theory is an intrinsic singularity. Its significance stems from two geometric events in the reduced phase space
Asteroid motion near the 3 : 1 resonance
A mapping model is constructed to describe asteroid motion near the 3 : 1 mean motion resonance with Jupiter, in the plane. The topology of the phase space of this mapping coincides with that of the

Numerical integration of periodic orbits in the main problem of artificial satellite theory
We describe a collection of results obtained by numerical integration of orbits in the main problem of artificial satellite theory (theJ2 problem). The periodic orbits have been classified according
Orbits Close to Asteroid 4769 Castalia
We use a radar-derived physical model of 4769 Castalia (1989 PB) to investigate close orbit dynamics around that kilometer-sized, uniformly rotating asteroid. Our methods of analysis provide a basis
Stationkeeping at libration points of natural elongated bodies
Collinear libration points are proposed as useful locations for the close survey of natural elongated bodies in rotation. The effect of the primary asphericity is introduced qualitatively by means of
Exterior gravitation of a polyhedron derived and compared with harmonic and mascon gravitation representations of asteroid 4769 Castalia
The exterior gravitation of a constant-density polyhedron is derived analytically in closed form. Expressions for potential, attraction, and gravity gradient matrix involve one logarithm term per
