There are various methods for changing the course of an asteroid/comet. Earth moves through the meteoroid stream of particles left from the passages of a comet. Gibbs applied his vector methods to the determination of planetary and comet orbits. The first script commissioned was "The Cosmic Comet". Halley was the first comet to be recognized as periodic. A star with a streaming tail, probably Halley's Comet, then appears. An example of typical Oort cloud comet could be C/2018 F4. The Cyclone was a performance model of the Comet.
