Description
Orbital changes at the moment of ejection are the bases of the present evaluation of survival probability for particles ejected from a comet. It is established that a portion of the dirty water-ice grains thus ejected can attain bound orbits. Surviving grains taking the orbits with perihelion distances of less than 7 AU completely lose their water-ice component, primarily due to sublimation. Grains moving on orbits with greater-than-7 AU perihelion distances change their orbits to a significant degree, due to the Poynting-Robertson effect, when grain radii are less than 100 microns, and are destroyed by collisions when grain radii are greater than 100 microns. 26 refs
