Semi-major axis (au) versus eccentricity and inclination (°) for fireballs observed by each network, along with 661 JFCs from the NASA HORIZONS database. The plot’s color scheme represents the outcome of 10 kyr simulations, indicating the percentage of clones per object that underwent significant gravitational interactions with Jupiter, sufficient to increase their perihelion distance to at least 2.5 au. This perihelion distance is critical as it delineates the inner boundary where cometary activity can commence, with water ice starting to sublimate. Objects colored closer to red in this plot suggest a higher dynamical affinity with typical JFC behavior.
