This study explores the novel concept of a planet intersecting the orbit of a small comet's fragment chain. Utilizing a simple multi-generational model of comet fragmentation, it analyzes the planet's interaction with the comet’s fragment chain and simulates probability distributions for both chain crossing and fragment capture. This model offers insights complementary to impact theories that seek to explain the Younger Dryas boundary. Moreover, the potential presence of cometary material in Earth's orbit due to crossing a comet’s fragment chain could profoundly influence climate patterns, with far-reaching implications for global agriculture and food production.
