“…It explains the sudden extinction of dinosaurs in an asteroid-Earth collision about 65 million years ago. The more recent collision of the comet Shoemaker-Levy 9's fragments with Jupiter further validates the collisional focus when the solar system's planets and satellites interact with cosmic bodies (Ipatov and Mather, 2004;Medvedev et al, 2016;Shustov et al, 2015;Sokolova et al, 2014). The singular collisions are complemented with a spectrum of non-collisional planet-small body interactions that range from tidal disruptions to many cosmogenic factors that in uence how a small body's orbit, for example, eventually evolves to form a meteoroid stream (Sokolova et al, 2013).…”

This article studies a planet whose orbit intersects the orbit of a small comet’s fragment chain. A simple, general, multi-generational model of comet fragmentation and fragment separation is developed, yielding the fragment distribution for each generation of the comet’s fragment chain. The fragment chain is used in analysis of the planet’s chain crossing and fragment capture. Simulating the chain crossing and fragment capture, the probability distributions for the chain crossing and fragment capture are calculated. The average probability for the planet crossing the fragment chain of a small, long period comet is 0.43 × 10− 3 per perihelion passage. The average probability for the planet crossing the fragment chain of a small, short period comet is 1.01 × 10− 3 per perihelion passage. For both, the average probability of fragment capture in chain crossing is 5.84 × 10− 2 per crossing. The probabilities calculated for the planet crossing a fragment chain and capturing fragments are higher than the planet-comet collision probability of the order of 10− 9 per perihelion passage for both the short period and long period comets, thus making chain crossing and fragment capture more probable planetary events.

“…For instance, it elucidates the abrupt extinction of dinosaurs resulting from an asteroid-Earth collision approximately 65 million years ago. Another compelling illustration is the more recent collision of fragments from the comet Shoemaker-Levy 9 with Jupiter, providing further validation of the collisional emphasis in the interactions between the solar system's planets, satellites, and cosmic bodies [1][2][3][4].…”

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.
