…in a three-to-one (written 3:1) resonance orbit with Jupiter. Consequently, once every three orbits, Jupiter and an asteroid in such an orbit would be in the same relative positions, and the asteroid would experience a gravitational force in a fixed direction. Repeated applications of that force would eventually change the…

- In meteorite: Cosmic-ray exposure ages of meteorites
…the asteroid belt until their orbits intersect a resonance—i.e., a region in the belt where they experience strong gravitational perturbations by the planets, particularly Jupiter—that puts the meteoroids in Earth-crossing orbits. The general drop-off in the frequency of meteorites with older exposure ages and the upper limit for most stony…
