                         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

                         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
