abstract = "The orbital dynamics of a spacecraft orbiting around irregular
small celestial bodies is a challenging problem. Difficulties to
model the gravity field of these bodies arise from the poor
knowledge of the exact shape as observed from the Earth. In order
to understand the complex dynamical environment in the vicinity of
irregular asteroids, several studies have been conducted using
simplified models. In this work, we investigate the qualitative
dynamics in the vicinity of an asteroid with an arched shape using
a tripole model based on the existence of three mass points linked
to each other by rods with given lengths and negligible masses. We
applied our results to some real systems, namely, asteroids 8567,
243 Ida and 433 Eros and also Phobos, one of the natural
satellites of Mars. RESUMEN: La din´amica orbital de un sat´elite
en torno a un cuerpo celeste irregular es un problema abierto. La
dificultad de modelar el campo gravitatorio de esos cuerpos surge
del pobre conocimiento que tenemos sobre sus formas, al
observarlos desde la Tierra. Para entender el complejo entorno
din´amico de los asteroides irregulares se han propuesto modelos
simplistas. En este trabajo, investigamos cualitativamente la
din´amica en el entorno de un asteroide en forma de arco, mediante
un modelo de tripolo basado en tres puntos masa unidos por barras
de longitudes determinadas y masas despreciables. Aplicamos
nuestros resultados a algunos cuerpos reales, como el asteroide
8567, el 243 Ida, y el 433 Eros, as´\ı como a Phobos, uno de
los sat´elites naturales de Marte.",
