We model the interplanetary dust distribution in the outer Solar System.

Sources are Edgeworth-Kuiper Belt, Jupiter-family, Halley-type, and Oort Cloud comets.

Dust densities are constrained by Pioneer 10 and New Horizons Student Dust Counter.

Fluxes from several families are important at each of the outer planets.

O influx from dust to outer planet atmospheres compared to photochemical constraints.
