Abstract

Asteroids and comets are remnants from the era of solar system formation over 4.5 billion years ago and therefore allow us to address two fundamental questions in astronomy: what was the nature of our protoplanetary disk, and how did the process of planetary accretion occur? The objects we see today have suffered many geophysically relevant processes in the intervening eons that have altered their surfaces, interiors, and compositions. In this chapter, we review our understanding of the origins and evolution of these bodies, discuss the wealth of science returned from spacecraft missions, and motivate important questions to be addressed in the future.
