Small-Body Reservoirs & Solar System Architecture: Physical Mechanisms

Asteroids, comets, trans-Neptunian objects, and other small bodies occupy dynamically distinct reservoirs that preserve information about Solar-System formation and later gravitational rearrangement. Small bodies constrain the early location and migration of planets, preserve primitive chemistry, supply impact hazards, and may have delivered volatiles and organic material to young terrestrial planets.

supported

Small-body reservoirs are leftovers of planet formation whose present architecture was sculpted by collisions, resonances, and gravitational scattering by the planets.
