Title: Interplanetary dust - Possible implications for comets and presolar interstellar grains
Abstract: Interplanetary dust is important to studies of the origin of the solar system because it is material from comets and asteroids, the smallest surviving bodies from the early solar system. The fact that comets are the major suppliers of the millimeter meteoroids which produce optical meteors suggests that a significant fraction of the submillimeter portion of the meteoroid complex is also cometary material. While comets are probably the major source, it is important to remember that the dust presently impacting the earth was probably generated by a number of different parent bodies. The collection of interplanetary dust is considered and a description is presented of the physical properties of interplanetary dust, taking into account the structure, elemental composition, and mineralogy.
