Stable regions, favorable regions to find new satellites, were found around the two large bodies Pluto and Charon, coorbital to Nix and Hydra and also in a small region between the orbits of these two small satellites (Giuliatti Winter et al., 2010 and Pires dos Santos et al., 2010). The discovery of the small satellites Nix and Hydra, located in the external region of the Pluto-Charon binary system, increased the possibility of rings in this system. If this ring were composed of dust particles the effects of non-gravitational forces, such as the solar radiation pressure, has also to be taken into account. In this work we analyzed the effects of the solar radiation pressure on a sample of micrometer-sized dust grains in circular orbits around Pluto, assuming spherical dust grains and neglecting the planetary shadow and the light reflected from the planet. As result we verified that the Poynting-Robertson component of the solar radiation force is responsible for the decreasing in the semimajor axis of the particles leading them to a collision with the planet on a timescale between 1.47 x 106 years (particles of 1 micrometer-sized in radius) and 1.47 x 107 years (particles of 10 micrometer-sized in radius), according to the value estimated by Burns et al. (1979); while the radiation pressure component causes an increase in the eccentricity of the particles, leading particles smaller than 10 micrometer-sized in radius to collide with the planet in less than 10 years. For those particles closer to the planet, located at 20 times Pluto's radius, the effect of radiation pressure is weaker. We also analyzed the collisions between these dust particles and the four massive bodies Pluto-Charon-Nix and Hydra.
