The Cassini mission sent a large amount of data concerning the G~ring of Saturn and the small satellites located between the G and E rings. These small satellites, Anthe, Methone, Pallene and Aegaeon, were detectedthrought a carefully analysis of the Cassini images. These images also reveleadarcs coorbital to these small satellites. In this project will be analysed the dynamics which evolve the satellite Aegaeon, in resonance with the satellite Mimas, and the small dust particles located at the arc of the G~ring. These dust particles can be the result of collisions between interplanetary objects and the satellite Aegaeon. This system will be also under the effects of the Solar RadiationPressure and the gravity coefficient ($J_2$) of the planet Saturn. (AU)
