Temporary orbital capture of ejecta from comets and asteroids : Application to the Deep Impact experiment

The trajectories of dust particles ejected from the surface of a comet or asteroid after a cratering impact are influenced by the interplay of solar radiation pressure, solar tide, cometary outgassing (for comets) and the body’s irregular gravity field. In this paper we evaluate the ability of these forces to cause ejecta to become captured in temporary… CONTINUE READING
