Abstract

Many meteor streams are undergoing rapid orbital evolution due to planetary perturbations. In time periods as short as one hundred years, some stream's orbits can be swept right across the earth's orbit and will hence only produce a shower during this time. Others are undergoing much slower evolution and stay close to the earth's orbit for thousands of years. Starting from the working list of meteor streams produced by Cook (1973), the orbital evolution of every stream on a closed orbit has been calculated going both backwards and forwards from the present for one thousand years.
