Alternatively, it is possible that the interaction of the planets with a comet can move its orbit too far from the Earth to be seen or even eject it from the Solar System, as is believed to have happened in the case of Lexell's Comet.
U drugom slučaju međudjelovanje s planetama može pomaknuti kometovu orbitu predaleko od Zemlje da bi ju se moglo vidjeti ili ju čak izbaciti iz Sunčeva sustava, kao što se smatra da se dogodilo Lexellovu kometu.
