At a GlanceAI
Shows that many weak mean-motion resonances can cumulatively push asteroids onto Earth-crossing orbits.
SummaryAI
The study argues that asteroid transport toward terrestrial-planet-crossing orbits can be driven not only by a few strong resonances, but by a web of numerous weak mean-motion resonances. By emphasizing the cumulative role of these subtle dynamical pathways, it broadens the standard picture of how near-Earth asteroids are supplied from the main belt. The implication is that the delivery of impactor populations may be more spatially widespread and dynamically complex than models focused on only the strongest resonances.
