Multitarget flyby missions to asteroids and comets are attractive candidates for solar electric propulsion (SEP) application because SEP can efficiently provide the thrust required for carefully chosen sequences of encounters. In this paper, techniques for finding encounter sequences for these missions are described, and examples involving flyby and rendezvous missions to P/Encke, P/Kopff and 20/Massalia are presented. In addition, examples of four asteroid flyby sequences are given. Encounters typically have flyby speeds on the order of 5-10 km/sec and are limited only by navigational capability as regards flyby distance, which is taken as zero in the study. Flights traversing the asteroid belt can be modified by SEP to pass one or more asteroids, and the performance penalty is small if the encounters are properly spaced.
