We consider the influx of a collinear stream of interstellar particles (ISPs) into the Solar System for the case where non-gravitational forces are negligible (particle size m) and model their Keplerian trajectories to yield the expected heliocentric orbits on impact with the Earth. The heliocentric orbital characteristics of such a stream of ISPs undergo cyclic seasonal variations allowing the determination of the stream inflow direction and far-Sun speed the orbit element signatures.
