A simple model is constructed for the evolution of dust ejected from long period comets at perihelion. The initial distribution of particle states are modeled using the Whipple formula for the emission velocity of comet dust, then modification of the orbits by radiation pressure are accounted for. The initial ejected cloud and its lifetime then can be analytically computed. The time history of the particles in this stream are then followed by numerical integration accounting for Poynting-Robertson drag and gravitational perturbations of the planets. The structure of the resulting stream is displayed.
