Why So Many Meteorites Come From The Same Place
Because of space physics, one faraway asteroid is likely the progenitor of almost a third of all the meteorites on Earth.

Meteor: A meteoroid that has entered the Earth’s atmosphere.
Meteorite: A meteor that hits the Earth.
Orbital resonance: A force that occurs when orbiting bodies exert a regular, periodic gravitational influence on each other, because of the length of their relative orbits.
Kirkwood Gap: A dip in the distribution of main belt asteroids that correspond to the locations of orbital resonances with Jupiter.
