  author={John E. Chambers},
Abstract Periodic comet Swift-Tuttle is the largest known object in the Solar System whose current orbit allows it to make repeated close approaches to the Earth. As such it poses a significant impact hazard. In addition, P/Swift-Tuttle possesses the second longest observing are of any comet, with recorded observations spanning two millennia. These data place extremely tight constraints on the current orbit. This paper analyzes the likely dynamical evolution of P/Swift-Tuttle for 40,000 years… CONTINUE READING
