Panel Selection: Primitive Bodies: Asteroids, comets, Phobos, Deimos, Pluto/Charon and other Kuiper belt objects, meteorites, and interplanetary dust.
Institution: Southwest Research Institute
We have no direct data on the interior structure of primitive bodies. The interior structure of asteroids is relevant to most solar system formation and evolution theories. Seismology is the only method for determining the interior structure for a range of sizes of asteroids to address.
