Prado Física, Astronomía y Matemáticas Methods general numerical asteroids minor planets 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. 2020 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171663009 https://www.redalyc.org/journal/571/57171663009/ https://www.redalyc.org/journal/571/57171663009/html/ https://www.redalyc.org/journal/571/57171663009/57171663009.epub https://www.redalyc.org/journal/571/57171663009/movil 10.22201/ia.01851101p.2020.56.02.09 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.56
