Abstract

In previous papers, the authors have demonstrated that most of the characteristics of the Geminid meteor stream can be explained in terms of a model where the stream particles are ejected from a cometary nucleus. It now seems fairly certain that object 1983TB is associated with the Geminid meteor stream but recent observations suggest that 1983TB is not the nucleus of a comet. A model for the formation of the stream based on a collision between two rock like bodies is described. It is found that this model can explain two observed characteristics but has difficulty in explaining the observed distribution of aphelion distances.
